❓ FAQ
QDoes and always return True/False?
ANo, it returns one of its operands: `0 and 'x'` returns `0`, and `1 and 'x'` returns `'x'`. Only when the result is used in an `if` condition is it judged by truthiness.
QWhat does short-circuiting in and mean?
AIt evaluates left to right and returns the first falsy value immediately, without ever evaluating the right side. For example, in `a and b`, when `a` is falsy `b` is not evaluated — handy for safely writing things like `.x` access.
QWhat is the difference between and and &?
A`and` is boolean logic (short-circuits, returns an operand); `&` is bitwise AND (works bit by bit on ints, or set intersection on sets). `1 & 2` is `0` while `1 and 2` is `2` — completely different behavior.
