Any & All in Python

Any and All are two built ins provided in python used for successive And/Or.

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]))

All


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.
