Moved

Now located at https://github.com/JeffPaine/beautiful_idiomatic_python.

Why it was moved

Github gists don't support Pull Requests or any notifications, which made it impossible for me to maintain this (surprisingly popular) gist with fixes, respond to comments and so on. In the interest of maintaining the quality of this resource for others, I've moved it to a proper repo. Cheers!

List Comprehensions and Generator Expressions

result = []
for i in range(10):
s = i ** 2
    result.append(s)
print sum(result)

IndentationError: expected an indented block

Factor-out temporary contexts

@contextmanager
def redirect_stdout(fileobj):
    oldstdout = sys.stdout
    sys.stdout = fileobj
    try:
        yield fieldobj    # 'fieldobj' may be 'fileobj'?
    finally:
        sys.stdout = oldstdout

I've addressed all comments here and moved this gist to a proper repo: https://github.com/JeffPaine/beautiful_idiomatic_python (so Pull Requests can be received and I get notifications, which isn't possible for gists).

If you have any other fixes / comments, please make them on that repo as I won't be checking back here again in the future. Thanks a lot!
