Exploring how to simplify code using Boolean Operators.

Conditionals

All programs can be written without using any Boolean operators. By using them your code can be more simple and easy to read. In this activity you will explore how Boolean operators can simplify code.

  1. Fill in the following table. For each row of the table, write what the following function prints to the terminal window. Put the result in the column on the right.

    def a_func(a, b):
    if a < b:
        is_a_less_than_b = True
    else:
        is_a_less_than_b = False
    return is_a_less_than_b
print(a_func(1, 2))
print(a_func(2, 1))
print(a_func(1, 1))

    def a_func(a, b):
    return a < b
print(a_func(1, 2))
print(a_func(2, 1))
print(a_func(1, 1))

    def a_func(a, b):
    is_a_less_than_b_and_0 = False
    if a < b:
        if a < 0:
            is_a_less_than_b_and_0 = True
    return is_a_less_than_b_and_0
print(a_func(-2, -1))
print(a_func(1, 2))
print(a_func(2, 1))
print(a_func(-1, -2))

    def a_func(a, b):
    return a < b and a < 0
print(a_func(-2, -1))
