Python standard library: Built-in function any (iterable)

Returns trueif all elements of an object that can iterate are true if there is one element, otherwise Falseis returned. Or the iterator object is empty and also returns False. This function is mainly used to determine whether the list, tuple, dictionary and other objects have elements of True, increase the speed of computation, the equivalent code is as follows:

def any (iterable):

For element in iterable:

If element:

Return True

Return False

Example:

#any () function A = []B = {}c = (1, 3, 4) d = (None, 1, 3) print (' A: ', any (a), ' B: ', any (b), ' C: ', any (c), ' d: ', any (d))

The output results are as follows:

A:false B:false c:true D:true
