Python Boolean

A boolean is a value that is either True or False. When two values are compared, the expression is evaluated and a boolean value is returned.

Example

print(70 > 50)
print(55 < 19)
print(10 == 10)
  

Output

A boolean is commonly used with control statements to determine the flow of a program.

Example:

x = 10
y = 20
if x > y:
    print("x is greater than y")
else:
    print("y is greater than x")
  

Output
