why we use a.any() or a.all() in python code example

Example 1: any in python

The any() function takes an iterable (list, string, dictionary etc.) in Python.

The any() function returns the boolean value:

True if at least one element of an iterable is true
False if all elements are false or if an iterable is empty

Example:
some_list = [1, 2, 3]
print(any(some_list)) # True
another_list = []
print(any(another_list)) # False

Example 2: any python

# True since 1,3 and 4 (at least one) is true
l = [1, 3, 4, 0]
print(any(l))

# False since both are False
l = [0, False]
print(any(l))

# True since 5 is true
l = [0, False, 5]
print(any(l))
