Python Boolean expression is an expression that evaluates to produce a result which is a Boolean value. An if statement uses the equal operator == to test if two values are equal and produce (or yield) a Boolean value.
The Boolean values in Python are
False, typically used to control if-statements and while-loops.
Boolean expression Python example
Simple example code that returns a True or False value.
# Is three greater than two?
print(1 > 2)
# Is the number of characters in the string "Hello" equal to one?
print(len("Hello") == 1)
# Is 5 equal to 3 + 2?
print(5 == 3 + 2)
# Is four greater than or equal to nine?
print(2 + 2 >= 10)
# Is seven not equal to twelve?
print(5 != 10)
Boolean expression in the if else statement
my_number = 24 if my_number % 2 == 0: print(my_number, "is even.") else: print(my_number, "is odd.")
Python Comparison Operators
Mostly Boolean expressions are expressions that use comparison operators.
|x == y||x equals y|
|x != y||x does not equal y, x is not equal to y|
|x >= y||x is greater than or equal to y|
|x <= y||x is less than or equal to y|
