Learn how to use Python's if __name__ == "__main__" idiom to control code execution. Discover its purpose, mechanics, best practices, and when to use or avoid it. This tutorial explores its role in managing script behavior and module imports for clean an
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 ...
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...
In Python, when you write a code, the interpreter needs to understand what each part of your code does. Tokens are the smallest units of code that have a specific purpose or meaning. Each token, like a keyword, variable name, or number, has a role in telling the computer what to do....
+ 1 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 ...

The whole point of “python is cleaner“, because your code does not work anymore correctly without correct indentation is nonsense. The problem they tried to fix, is more or less non-existent due to smart editors and auto-formatting. Or do you code in notepad?
This is where Swift 4.1's new keyDecodingStrategy property comes in: it’s set to .useDefaultKeys by default, which does a direct mapping of JSON names to Swift properties. However, if you change it to .convertFromSnakeCase then Codable handles the name conversion for us. For example: let...
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...
