Hi,
I am looking for a python SOAP 1.2 client but it seems that it does not exist . All of the existing clients are either not maintainted or only compatible with SOAP 1.1:
suds
SOAPpy
ZSI
I have a string of HTML stored in a database. Unfortunately it contains characters such as ®
I want to replace these characters by their HTML equivalent, either in the DB itself or using a Find Replace in my Python / Django code.
Any suggestions on how I can do this?
I want to run:
python somescript.py somecommand
But, when I run this I need PYTHONPATH to include a certain directory. I can't just add it to my environment variables because the directory I want to add changes based on what project I'm running. Is there a way to alter PYTHONPATH while running a script? Note: I don't even have a PYTHONPATH variable, so I don't need to worry about appending to it vs overriding it during running of this script.
How are lists in python stored internally? Is it an array? A linked list? Something else?
Or does the interpreter guess at the right structure for each instance based on length, etc.
If the question is implementation dependent, what about the classic CPython?
I have a question about idioms and readability, and there seems to be a clash of Python philosophies for this particular case:
I want to build dictionary A from dictionary B. If a specific key does not exist in B, then do nothing and continue on.
Which way is better?
try:
A["blah"] = B["blah"]
except KeyError:
pass
or
if "blah" in B:
A["blah"] = B["blah"]
"Do and ask for forgiveness" vs. "simplicity and explicitness".
Which is better and why?
im trying to build android from source on ubuntu 10.04. when i enter the repo command:
repo init -u git://android.git.kernel.org/platform/manifest.git -b eclair
it get this error back
exec: 23: python: not found
any ideas.
One of the ideas of Python's design philosophy is "There should be one ... obvious way to do it." (PEP 20), but that can't always be true. I'm specifically referring to (simple) if statements versus boolean evaluation. Consider the following:
if words:
self.words = words
else:
self.words = {}
versus
self.words = words or {}
With such a simple situation, which is preferable, stylistically speaking? With more complicated situations one would choose the if statement for readability, right?
Python has string.find() and string.rfind() to get the index of a substring in string.
I wonder, maybe there is something like string.find_all() which can return all founded indexes (not only first from beginning or first from end)?
For example:
string = "test test test test"
print string.find('test') # 0
print string.rfind('test') # 15
#that's the goal
print string.find_all('test') # [0,5,10,15]
Can we initialize python objects with statement like this:
a = b = c = None
it seems to me when I did a = b = c = list() will cause circular reference count issue.
Please give your expert advice.
Contents of check.py:
from multiprocessing import Process
import time
import sys
def slp():
time.sleep(30)
f=open("yeah.txt","w")
f.close()
if __name__=="__main__" :
x=Process(target=slp)
x.start()
sys.exit()
In windows 7, from cmd, if I call python check.py, it doesn't immediately exit, but instead waits for 30 seconds. And if I kill cmd, the child dies too- no "yeah.txt" is created.
How do I make ensure the child continues to run even if parent is killed and also that the parent doesn't wait for child process to end?
Does anyone know of a memory efficient way to generate very large xml files (e.g. 100-500 MiB) in Python?
I've been utilizing lxml, but memory usage is through the roof.
For some reason this function confused me:
def protocol(port):
return port == "443" and "https://" or "http://"
Can somebody explain the order of what's happening behind the scenes to make this work the way it does.
I understood it as this until I tried it:
Either A)
def protocol(port):
if port == "443":
if bool("https://"):
return True
elif bool("http://"):
return True
return False
Or B)
def protocol(port):
if port == "443":
return True + "https://"
else:
return True + "http://"
Is this some sort of special case in Python, or am I completely misunderstanding how statements work?
I want to know how to run a progress bar and some other work simultaneously, then when the work is done, stop the progress bar in Python (2.7.x)
import sys, time
def progress_bar():
while True:
for c in ['-','\\','|','/']:
sys.stdout.write('\r' + "Working " + c)
sys.stdout.flush()
time.sleep(0.2)
def work():
*doing hard work*
How would I be able to do something like:
progress_bar() #run in background?
work()
*stop progress bar*
print "\nThe work is done!"
Hi
I have a list of points as shown below
points=[ [x0,y0,v0], [x1,y1,v1], [x2,y2,v2].......... [xn,yn,vn]]
Some of the points have duplicate x,y values. What I want to do is to extract the unique maximum value x,y points
For example, if I have points [1,2,5] [1,1,3] [1,2,7] [1,7,3]
I would like to obtain the list [1,1,3] [1,2,7] [1,7,3]
How can I do this in python
Thanks
given a list of python strings, how can I automatically convert them to their correct type? Meaning, if I have:
["hello", "3", "3.64", "-1"]
I'd like this to be converted to the list
["hello", 3, 3.64, -1]
where the first element is a stirng, the second an int, the third a float and the fourth an int.
how can I do this? thanks.
I'm using the following code to hide stderr on Linux/OSX for a Python library I do not control that writes to stderr by default:
f = open("/dev/null","w")
zookeeper.set_log_stream(f)
Is there an easy cross platform alternative to /dev/null? Ideally it would not consume memory since this is a long running process.
Cant download any pyhton windows modules and install. I wanted to experiment with scrapy framework and stackless but unable to install due to error "Python veIrsion 2.6 required, which was not found in the registry".

Hi,
I was wondering if there is a way to automatically run commands on entering the python shell as you would with the .bash_profile or .profile scripts with bash. I would like to automatically import some modules so I don't have to type the whole shebang everytime I hop into the shell.
Thanks,
I'm writing a Python application, that I want to later migrate to GAE.
The new "Task Queues" API fulfills a requirement of my app, and I want to simulate it locally until I have the time to migrate the whole thing to GAE.
Does anyone know of a compatible module I can run locally?
Windows XP, Python2.5:
hash('http://stackoverflow.com') Result: 1934711907
Google App Engine (http://shell.appspot.com/):
hash('http://stackoverflow.com') Result: -5768830964305142685
Why is that? How can I have a hash function which will give me same results across different platforms (Windows, Linux, Mac)?
I have two floats in Python that I'd like to subtract, i.e.
v1 = float(value1)
v2 = float(value2)
diff = v1 - v2
I want "diff" to be computed upto two significant figures, that is compute it using %.2f of v1 and %.2f of v2. How can I do this? I know how to print v1 and v2 up to two decimals, but not how to do arithmetic like that.
thanks.
