all()
all() is a Python function in the Built-in Functions category. Returns True if all elements of the iterable are truthy. The syntax is all(iterable). Parameters: iterable — any iterable. Returns: Boolean. A typical example: all([1, 2, 3]) # True
all([1, 0, 3]) # False
all([]) # True (vacuously true). A close sibling is print(), which prints objects to the text stream, separated by `sep` and followed by `end`. A close sibling is len(), which returns the length (number of items) of an object. Works with sequences, collections, and strings. A close sibling is range(), which returns an immutable sequence of numbers. Commonly used in for loops. A close sibling is type(), which returns the type of an object, or creates a new type with three arguments.
