import os
def touch(fname, times=None):
with open(fname, 'a'):

How to get one value at a time from a generator function in Python?
...
In Python <= 2.5, use gen.next(). This will work for all Python 2.x versions, but not Python 3.x
In Python >= 2.6, use next(gen). This is a built in function, and is clearer. It will also work in Python 3.

...
For python 2.5, and when working with pydev, it's a bit hard. It appears that pydev doesn't use the test suite, but finds all individual test cases and runs them all separately.

Abstract methods in Python [duplicate]
...functionality in Python 2.6 and later, but there are no options for Python 2.5 and earlier. The abc package is not a new feature of Python; instead, it adds functionality by adding explicit "does this class say it does this?" checks, with manually-implemented consistency checks to cause an error dur...

If you have a git repo cool-app, cd to root (cd cool-app), run git worktree add ../cool-app-feature-A feature/A. This checks out the branch feature/A in it's own new dedicated directory,...
How can I reverse a NSArray in Objective-C?
...26
2. Iterating over an reverseObjectEnumerator
This is between 1.5x and 2.5x slower:
NSDate *methodStart = [NSDate date];
NSMutableArray *array = [NSMutableArray arrayWithCapacity:[anArray count]];
NSEnumerator *enumerator = [anArray reverseObjectEnumerator];
for (id element in enumerator) {

Best way to test exceptions with Assert to ensure they will be thrown
...
As of v 2.5, NUnit has the following method-level Asserts for testing exceptions:
Assert.Throws, which will test for an exact exception type:

And As...
