Python all() Function

The all() function is one of Python's built-in functions. It takes an iterable as input and returns True if all elements in the iterable are truthy (non-zero, non-empty, not None, etc.), otherwise it returns False.

Example Code

a = [1, 2, 3]
b = [0, 1, 2]
c = [True, False, True]

print(all(a))  # Output: True, because all elements in a are non-zero and truthy
print(all(b))  # Output: False, because the first element in b is 0, which is falsy
print(all(c))  # Output: False, because the second element in c is False, which is falsy
