Good to know

  • any() is the opposite check of all(): "at least one" instead of "every".
  • It short-circuits: with a generator it stops reading as soon as it finds a truthy item.

  • all() · Return True if every item in an iterable is truthy, or if the iterable is empty. Stops at the first falsy item.
  • filter() · Keep only the items of an iterable for which a function returns True. Returns a lazy iterator, not a list.
  • bool() · Convert a value to True or False using Python's truth rules: zero, empty and None are False, everything else is True.
