Pythonknows which lines execute in the same context by their indentation depth. It can't determine which block the 'less-indented' code goes to; all it knows is that you can't back out a half step without first taking a half-step in. for i in range(9): codecodecode for j in...
How did Python find 5 in a dictionary containing 5.0? Python does this in constant time without having to scan through every item by using hash functions. When Python looks up a key foo in a dict, it first computes hash(foo) (which runs in constant-time). Since in Python it is requir...

While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of Python that you might be unaware of. I find it a nice way to learn the internals of a programming language, and I believe that you'll find it ...
