using block indent does mean that your code will take up more lines, as each indented line is typically on its own line. however, the amount of actual data storage used is minimal, and the benefits in terms of

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...
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...

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 ...
2. Those Python regexes are not even remotely as powerful as the Perl ones. Reply skorr March 26, 2021 at 11:15 pm Not only does Python have established and well-documented standards for writing beautiful Pythonic code, (PEP8), there are multiple utilities to help ensure your code is Pyth...
I originally wrote this over two years ago. It was getting a little long in the tooth, especially now that HTML5 has come along and made HTML far more beautiful than even XHTML 1.1 was. So I updated it! I can’t help butview sourceon every nice looking website I see. It’s like...
runs. it's purely a visual tool to help you and others read and understand the code more easily. however, some languages like python use indentation to define the scope of loops and functions, so in those cases, it does have a functional purpose. when should i use block indent in my ...
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 required that objects that compare equal also have the same ...
