Python all() Function

Python all() Function

The all() function in Python returns a Boolean value ‘True’ if all the items in iterable are true or if the iterable object is empty, else it returns False.




Iterable: An iterable object (list, tuple, dictionary)


This function returns a Boolean value true if all the items in an iterable are true else it returns false.

Example 1

# Python Program explaining 
# all() built-in function
# will return True and the same will be printed
print ('The all() function will return: ',all([True, True, True]))
# first item (False) and will return False.
print ('The all() function will return: ',all([False, True, True, False]))  
# This statement will return False, as all the iterables are False
print ('The all() function will return: ',all([False, False, False]))


The all() function will return:  True
The all() function will return:  False
The all() function will return:  False
