When are function-local variables are created? For example, in the following code is dictionary d1 created each time the function f1 is called or only once when it is compiled? def f1(): d1 = {1: 2, 3: 4} return id(d1) d2 = {1: 2, 3: 4} def f2(): return id(d2) Is it faster in general to define a dictionary within function...
I'm trying to create PNGs of letters from the fonts on my system. Seems to work okay with TrueType fonts (.ttf) but not OpenType (.otf). The images formed are the same size but the actual letters appear much smaller with OpenType - see below. I'm using the ImageFont module from the Python Imaging library. There doesn't seem to be a way ...

From http://jaynes.colorado.edu/PythonIdioms.html "Build strings as a list and use ''.join at the end. join is a string method called on the separator, not the list.

Source Mediawiki markup Right now I'm using a variety of regexes to "parse" the data in the mediawiki mark-up into lists/dictionaries, so that elements within the article can be used. This is hardly the best method, as the number of cases that have to be made are large. How would one parse an article's mediawiki markup into a variety...
