I use triple double quotes for docstrings and raw string literals for regular expressions even … Read more

Iterate through a C++ Vector using a ‘for’ loop
Is there any reason I don’t see this in C++? Is it bad practice? No. It is not a bad practice, but the following approach renders your code certain flexibility. Usually, pre-C++11 the code for iterating over container elements uses iterators, something like: This is because it makes the code more flexible. All standard library containers … Read more
Python `if x is not None` or `if not x is None`?
There’s no performance difference, as they compile to the same bytecode: Stylistically, I try to avoid not x is y, a human reader might misunderstand it as (not x) is y. If I write x is not y then there is no ambiguity.
