Python function always returns a value True or False | Code

Assign the Boolean value to a variable and return it, it will make the function always returns a value True or False in Python. Discover code examples and different ways to implement functions in Python.

def foo(x, y):
    answer = False
    if x > y:
        answer = True
    else:
        answer = False
    return answer


print("X is Greater then Y: ", foo(12, 5))

Another example

A function that always returns True (or False) for every parameter (or even multiple parameters).

false = lambda *_: False
true  = lambda *_: True

In Python, a function can return a value of any data type, including True or False. For example, consider the following function that checks if a given number is even:

def is_even(num):
    if num % 2 == 0:
        return True
    else:
        return False

This function takes an argument num and returns True if the number is even, and False otherwise.

Alternatively, you can simplify the function using the ternary operator, like this:

def is_even(num):
    return True if num % 2 == 0 else False

This function does the same thing as the previous one, but in a more concise way.
