Python bool() Function in Linux

Introduction

In Python, the bool() function is used to convert a value to a boolean value (True or False) to check the truth according to the standard.

If the object has a value of None, False or equal to 0, the bool() function will return false. Except for all of the above, the bool() function will return true.

The following article is a detailed guide on how to use the bool() function in Python as we go through the section below.

x = []

print(bool(x))

y = 1

print(bool(y))

Output:

False

True

Output:

False

Example 2: Parity check program

def check(x):

return (bool(x % 2 == 0))

x = 4

if (check(x)):

print("Correct")

else:
