Any
- 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]))python tutorial - 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]))python tutorial - Output :
True
False
False
