  • Truly understand the threshold for document set in document library in SharePoint

    - by ybbest
    Recently, I am working on an issue with threshold. The problem is that when the user navigates to a view of the document library, it displays the error message “list view threshold is exceeded”. However, in the view, it has no data. The list view threshold limit is 5000 by default for the non-admin user. This limit is not the number of items returned by your query; it is the total number of items the database needs to read to calculate the returned result set. So although the view does not return any result but to calculate the result (no data to show), it needs to access more than 5000 items in the database. To fix the issue, you need to create an index for the column that you use in the filter for the view. Let’s look at the problem in details. You can download a solution to replicate this issue here. 1. Go to Central Admin ==> Web Application Management ==>General Settings==> Click on Resource Throttling 2. Change the list view threshold in web application from 5000 to 2000 so that I can show the problem without loading more than 5000 items into the list. FROM TO 3. Go to the page that displays the approved view of the Loan application document set. It displays the message as shown below although I do not have any data returned for this view. 4. To get around this, you need to create an index column. Go to list settings and click on the Index columns. 5. Click on the “Create a new index” link. 6. Select the LoanStatus field as I use this filed as the filter to create the view. 7. After the index is created now I can access the approved view, as you can see it does not return any data. Notes: List View Threshold: Specify the maximum number of items that a database operation can involve at one time. Operations that exceed this limit are prohibited.

  • SEO: Nested List vs List, Split Over Divs vs Definition List

    - by Jon P
    From an SEO perspective which, if any, is better: Option 1: Nested lists with h2 tags <ul id="mainpoints"> <li><h2>Powerful Analysis</h2> <ul> <li>Charting and indicators</li> <li>Daily trading signals</li> <li>Company health checks</li> </ul> </li> <li><h2>World Market Data</h2> <ul> [List Items removed for brevity] </ul> </li> <li><h2>Daily Market Data</h2> <ul> [List Items removed for brevity] </ul> </li> </ul> Option 2: Divs with h2 and lists <div id="mainpoints"> <div> <h2>Powerful Analysis</h2> <ul> <li>Charting and indicators</li> <li>Daily trading signals</li> <li>Company health checks</li> </ul> </div> <div> <h2>World Market Data</h2> <ul> [List Items removed for brevity] </ul> </div> <div> <h2>Daily Market Data</h2> <ul> [List Items removed for brevity] </ul> </div> </div> Option 3: Definition List <dl id="mainpoints"> <dt>Powerful Analysis</dt> <dd>- Charting and indicators</dd> <dd>- Daily trading signals</dd> <dd>- Company health checks</dd> <dt>World Market Data</dt> [List Items removed for brevity] <dt>Daily Market Data</dt> [List Items removed for brevity] </dl> My instincts tell me that semanticaly the pure list options (1 & 3) are the best and that h2 may be more SEO friendly (1 & 2) which would point to option 1 as being the best option. I do love the lean makeup of the definition list but will I take an SEO hit by losing the h2 tags? Before anyone asks, h2 is not valid markup in a dt tag. Are my instincts right with a nested list being the way to go?

  • Python list comprehension to return edge values of a list

    - by mvid
    If I have a list in python such as: stuff = [1, 2, 3, 4, 5, 6, 7, 8, 9] with length n (in this case 9) and I am interested in creating lists of length n/2 (in this case 4). I want all possible sets of n/2 values in the original list, for example: [1, 2, 3, 4], [2, 3, 4, 5], ..., [9, 1, 2, 3] is there some list comprehension code I could use to iterate through the list and retrieve all of those sublists? I don't care about the order of the values within the lists, I am just trying to find a clever method of generating the lists.

  • List comprehension from multiple sources in Python?

    - by Noah
    Is it possible to replace the following with a list comprehension? res = [] for a, _, c in myList: for i in c: res.append((a, i)) For example: # Input myList = [("Foo", None, [1, 2, 3]), ("Bar", None, ["i", "j"])] # Output res = [("Foo", 1), ("Foo", 2), ("Foo", 3), ("Bar", "i"), ("Bar", "j")]

  • Optimizing list comprehension to find pairs of co-prime numbers

    - by user3685422
    Given A,B print the number of pairs (a,b) such that GCD(a,b)=1 and 1<=a<=A and 1<=b<=B. Here is my answer: return len([(x,y) for x in range(1,A+1) for y in range(1,B+1) if gcd(x,y) == 1]) My answer works fine for small ranges but takes enough time if the range is increased. such as 1 <= A <= 10^5 1 <= B <= 10^5 is there a better way to write this or can this be optimized?

  • Testing if a list contains another list with Python

    - by None
    How can I test if a list contains another list. Say there was a function called contains: contains([1,2], [-1, 0, 1, 2]) # Returns [2, 3] (contains returns [start, end]) contains([1,3], [-1, 0, 1, 2]) # Returns False contains([1, 2], [[1, 2], 3) # Returns False contains([[1, 2]], [[1, 2], 3]) # Returns [0, 0] Edit: contains([2, 1], [-1, 0, 1, 2]) # Returns False contains([-1, 1, 2], [-1, 0, 1, 2]) # Returns False contains([0, 1, 2], [-1, 0, 1, 2]) # Returns [1, 3]

  • Hover effect for parent unordered list inherited by child list

    - by elvista
    I have a simple menu <ul id="menu"> <li class="leaf"><a href="#">Menu Item 1</a></li> <li class="leaf"><a href="#">Menu Item 2</a></li> <li class="expanded"><a href="#">Menu Item 3</a> <ul> <li class="leaf"><a href="#">Menu Item a</a></li> <li class="leaf"><a href="#">Menu Item b</a></li> <li class="leaf"><a href="#">Menu Item c</a></li> </ul> </li> <li class="leaf"><a href="#">Menu Item 4</a></li> </ul> and ul#menu li a:hover {font-weight:bold;} The problem I am facing is when I hover above a ul li li, the parent as well as all its siblings gets the hover effect. I only want the list item I hovered above to get the effect. I tried ul#menu li.leaf a: hover {..}, ul#menu li.expanded a: hover {..} , but even in that case, when I hover above li.expanded, it's child inherits the style. How do I fix this?

  • Python - List of Lists Slicing Behavior

    - by Dan Dobint
    When I define a list and try to change a single item like this: list_of_lists = [['a', 'a', 'a'], ['a', 'a', 'a'], ['a', 'a', 'a']] list_of_lists[1][1] = 'b' for row in list_of_lists: print row It works as intended. But when I try to use list comprehension to create the list: row = ['a' for range in xrange(3)] list_of_lists = [row for range in xrange(3)] list_of_lists[1][1] = 'b' for row in list_of_lists: print row It results in an entire column of items in the list being changed. Why is this? How can I achieve the desired effect with list comprehension?

  • understanding list[i-1] vs list[i]-1

    - by user3720527
    Hopefully this is a simple answer that I am just failing to understand. Full code is public static void mystery(int[] list) { for( int i = list.length - 1; i>1; i --) { if (list[i] > list[i - 1]) { list[i -1] = list[i] - 2; list[i]++; } } } } and lets say we are using a list of [2,3,4]. I know that it will output 2,2,5 but I am unclear how to actually work through it. I understand that the list.length is 3 here, and I understand that the for loop will only run once, but I am very unclear what happens at the list[i - 1] = list[i] - 2; area. Should it be list[2-1] = list[2] - 2? How does the two being outside the bracket effect it differently? Much thanks.

  • Using list comprehension in Python to do something similar to zip()?

    I'm a Python newbie and one of the things I am trying to do is wrap my head around list comprehension. I can see that it's a pretty powerful feature that's worth learning. cities = ['Chicago', 'Detroit', 'Atlanta'] airports = ['ORD', 'DTW', 'ATL'] print zip(cities,airports) [('Chicago', 'ORD'), ('Detroit', 'DTW'), ('Atlanta', 'ATL')] How do I use list comprehension so I can get the results as a series of lists within a list, rather than a series of tuples within a list? [['Chicago', 'ORD'], ['Detroit', 'DTW'], ['Atlanta', 'ATL']] (I realize that dictionaries would probably be more appropriate in this situation, but I'm just trying to understand lists a bit better). Thanks!

  • Python nested dict comprehension with sets

    - by Jasie
    Can someone explain how to do nested dict comprehensions? >> l = [set([1, 2, 3]), set([4, 5, 6])] >> j = dict((a, i) for a in s for i, s in enumerate(l)) >> NameError: name 's' is not defined I would have liked: >> j >> {1:0, 2:0, 3:0, 4: 1, 5: 1, 6: 1} I just asked a previous question about a simpler dict comprehension where the parentheses in the generator function were reduced. How come the s in the leftmost comprehension is not recognized?

  • Python: Repeat elements in a list comprehension?

    - by User
    I have the following list comprehension which returns a list of coordinate objects for each location. coordinate_list = [Coordinates(location.latitude, location.longitude) for location in locations] This works. Now suppose the location object has a number_of_times member. I want a list comprehension to generate n Coordinate objects where n is the number_of_times for the particular location. So if a location has number_of_times = 5 then the coordinates for that location will be repeated 5 times in the list. (Maybe this is a case for a for-loop but I'm curious if it can be done via list comprehensions)

    can we use elif in list comprehension? example : l = [1, 2, 3, 4, 5] for values in l: if values==1: print 'yes' elif values==2: print 'no' else: print 'idle' can we use list comprehension for such 2 if conditions and one else condition? foe example answer like : ['yes', 'no', 'idle', 'idle', 'idle'] I have done till now only if else in list comprehension.

  • Help with python list-comprehension

    - by leChuck
    A simplified version of my problem: I have a list comprehension that i use to set bitflags on a two dimensional list so: s = FLAG1 | FLAG2 | FLAG3 [[c.set_state(s) for c in row] for row in self.__map] All set_state does is: self.state |= f This works fine but I have to have this function "set_state" in every cell in __map. Every cell in __map has a .state so what I'm trying to do is something like: [[c.state |= s for c in row] for row in self.map] or map(lambda c: c.state |= s, [c for c in row for row in self.__map]) Except that neither works (Syntax error). Perhaps I'm barking up the wrong tree with map/lamda but I would like to get rid on set_state. And perhaps know why assignment does not work in the list-comprehension

  • Postfix/Procmail mailing list software

    - by Jason Antman
    I'm looking for suggestions on mailing list software to use on an existing server running Postfix/Procmail. Something relatively simple. requirements: 1 list, < 50 subscribers list members dumped in a certain file by a script (being pulled from LDAP or MySQL on another box) Handles MIME, images, etc. Moderation features No subscription/unsubscription - just goes by the file or database. Mailman is far too heavy-weight, and doesn't seem to play (easily) with Postfix/Procmail. I'm currently using a PHP script that just receives mail as a user, reads a list of members from a serialized array (file dumped on box via cron on the machine with the MySQL database containing members) and re-mails it to everyone. Unfortunately, we now need moderation capabilities, and I don't quite feel like adding that to the PHP script if there's already something out there that does it. Thanks for any tips. -Jason

  • python: how to convert list of lists into a single nested list

    - by Bhuski
    I have a python list of lists as shown below: mylist=[ [['orphan1', ['some value1']]], [['parent1', ['child1', ['child', ['some value2']]]]], [['parent1', ['child2', ['child', ['some value3']]]]] ] I need to convert the above list to some thing like this: result=[ ['orphan1', ['some value1']], ['parent1', ['child1', ['child', ['some value2']]], ['child2', ['child', ['some value3']]]] ] Kindly help me approach this problem. I have given only simple list. In actual scenario here, in my list, even grand parents/grand childs are there. How much ever deep the input nested list is, I need to convert it to a single nested list, with common list elements (parents and grand parents) appearing only once. (but the next to innermost list element('child' in above example) should appear as many times it occurs in the input list. I have been trying to do this last two days, but did not end up with working solution :(. I need to use the output in django template filter: unordered_list so that the resultant nested list appears as a nested unordered list in my html page ..

  • Update a list from another list

    - by Langali
    I have a list of users in local store that I need to update from a remote list of users every once in a while. Basically: If a remote user already exists locally, update its fields. If a remote user doesn't already exist locally, add the user. If a local user doesn't appear in the remote list, deactivate or delete. If a local user also appears in the remote list, update its fields. Just a simple case of syncing the local list. Is there a better way to do this in pure Java than the following? I feel gross looking at my own code. public class User { Integer id; String email; boolean active; //Getters and Setters....... public User(Integer id, String email, boolean active) { this.id = id; this.email = email; this.active = active; } @Override public boolean equals(Object other) { boolean result = false; if (other instanceof User) { User that = (User) other; result = (this.getId() == that.getId()); } return result; } } public static void main(String[] args) { //From 3rd party List<User> remoteUsers = getRemoteUsers(); //From Local store List<User> localUsers =getLocalUsers(); for (User remoteUser : remoteUsers) { boolean found = false; for (User localUser : localUsers) { if (remoteUser.equals(localUser)) { found = true; localUser.setActive(remoteUser.isActive()); localUser.setEmail(remoteUser.getEmail()); //update } break; } if (!found) { User user = new User(remoteUser.getId(), remoteUser.getEmail(), remoteUser.isActive()); //Save } } for(User localUser : localUsers ) { boolean found = false; for(User remoteUser : remoteUsers) { if(localUser.equals(remoteUser)) { found = true; localUser.setActive(remoteUser.isActive()); localUser.setEmail(remoteUser.getEmail()); //Update } break; } if(!found) { localUser.setActive(false); // Deactivate } } }

  • Advanced Python list comprehension

    - by Yuval A
    Given two lists: chars = ['ab', 'bc', 'ca'] words = ['abc', 'bca', 'dac', 'dbc', 'cba'] how can you use list comprehensions to generate a filtered list of words by the following condition: given that each word is of length n and chars is of length n as well, the filtered list should include only words that each i-th character is in the i string in words. In this case, we should get ['abc', 'bca'] as a result. (If this looks familiar to anyone, this was one of the questions in the previous Google code jam)

  • filtering elements from list of lists in Python?

    - by user248237
    I want to filter elements from a list of lists, and iterate over the elements of each element using a lambda. For example, given the list: a = [[1,2,3],[4,5,6]] suppose that I want to keep only elements where the sum of the list is greater than N. I tried writing: filter(lambda x, y, z: x + y + z >= N, a) but I get the error: <lambda>() takes exactly 3 arguments (1 given) How can I iterate while assigning values of each element to x, y, and z? Something like zip, but for arbitrarily long lists. thanks, p.s. I know I can write this using: filter(lambda x: sum(x)..., a) but that's not the point, imagine that these were not numbers but arbitrary elements and I wanted to assign their values to variable names.
