• What is the python "with" statement designed for?

  - by fmark

  I came across the Python with statement for the first time today. I've been using Python lightly for several months and didn't even of its existence! Given its somewhat obscure status, I thought it would be worth asking: What is the Python with statement designed to be used for? What do you use it for? Are their any gotchas I need to be aware of, or common anti-patterns associated with its use?

• One Line 'If' or 'For'...

  - by aTory

  Every so often on here I see someone's code and what looks to be a 'one-liner', that being a one line statement that performs in the standard way a traditional 'if' statement or 'for' loop works. I've googled around and can't really find what kind of ones you can perform? Can anyone advise and preferably give some examples? For example, could I do this in one line: example = "example" if "exam" in example: print "yes!" Or: for a in someList: list.append(splitColon.split(a))

• running code if try statements were successful in python

  - by None

  I was wondering if in python there was a simple way to run code if a try statement was successful that wasn't in the try statement itself. Is that what the else or finally commands do (I didn't understand their documentation)? I know I could use code like this: successful = False try: #code that might fail successful = True except: #error handling if code failed if successful: #code to run if try was successful that isn't part of try but I was wondering if there was a shorter way .

• What problems are solved with R6RS Scheme's make-variable-transformer?

  - by Michael Conner

  While looking at the syntax-case section in R6RS, I saw the keyword make-variable-transformer, described as an identifier macro. The example given is very minimal, and I am not groking why it is necessary, or what use-cases require it. Finding additional examples of its use is also proving difficult. Presumably it makes some form of syntax transformation possible, or more elegant?

• SQL Insert into ... values ( SELECT ... FROM ... )

  - by Shadow_x99

  I am trying to insert into a table using the input from another table. Although this is entirely feasible for many database engines, I always seem to struggle to remember the correct syntax for the SQL-Engine of the day (MySQL, Oracle, SQLServer, Informix, DB2). I've been wondering if there is a silver-bullet syntax coming from an SQL Standards (For example, SQL92) that would allow me to insert the values without worrying about the underlying database.
