How to return 'false' because all elements are 'false'?
The given list is:
data = [False, False, False]
The Python all() function returns true if all the elements of a given iterable (List, Dictionary, Tuple, set, etc.) are True, else it returns False. It also returns True if the iterable object is empty.
🔸 The Built-in bool() Function You can check if a value is either truthy or falsy with the built-in bool() function. According to the Python Documentation, this function: Returns a Boolean value, i.e. one of True or False .
def is_list_even() returns true if all integers in the list are even and false otherwise. def is_list_odd() returns true if all integers in the list are odd and false otherwise.
To check if the item exists in the list, use Python “in operator”. For example, we can use the “in” operator with the if condition, and if the item exists in the list, then the condition returns True, and if not, then it returns False.
Using any
:
>>> data = [False, False, False] >>> not any(data) True
any
will return True if there's any truth value in the iterable.
