Any and All are two built ins provided in python used for successive And/Or.
Returns true if any of the items is True. It returns False if empty or all are false. Any can be thought of as a sequence of OR operations on the provided iterables.
It short circuit the execution i.e. stop the execution as soon as the result is known.
Syntax : any(list of iterables)
# Since all are false, false is returned print (any([False, False, False, False])) # Here the method will short-circuit at the # second item (True) and will return True. print (any([False, True, False, False])) # Here the method will short-circuit at the # first (True) and will return True. print (any([True, False, False, False])) |
Output :
False True True
Returns true if all of the items are True (or if the iterable is empty). All can be thought of as a sequence of AND operations on the provided iterables. It also short circuit the execution i.e. stop the execution as soon as the result is known.
Syntax : all(list of iterables)
# Here all the iterables are True so all # will return True and the same will be printed print (all([True, True, True, True])) # Here the method will short-circuit at the # first item (False) and will return False. print (all([False, True, True, False])) # This statement will return False, as no # True is found in the iterables print (all([False, False, False])) |
Output :
True False False
