❓ FAQ
QAre `False` and `0` equal?
A`False == 0` is `True` (since `bool` is a subclass of `int`), but `False is 0` is `False`. Note that «equal to False» and «falsy» are two different things.
QWhich values are considered falsy in a condition?
A`False`, `0`, `0.0`, the empty string `''`, empty list `[]`, empty tuple `()`, empty dict `{}`, empty set `set()`, `None`, plus cases where a custom object's `__bool__` returns `False` or `__len__` returns 0.
QCan I check whether a variable is empty with `if not x`?
AYes, `not x` is `True` for empty strings, empty lists, `0`, and `None`. But if `x` is a NumPy array, `not x` may raise «truth value of an array is ambiguous»; in that case use an explicit comparison.
