As Alex’s programming journey continued, they learned about Python boolean values. Booleans are a data type that represent either True or False. Alex found this to be an interesting concept and was eager to learn more about it.
One day, Alex was working on a program that needed to determine if a number was even or odd. They used the modulus operator % to calculate the remainder when the number was divided by 2. If the remainder was 0, the number was even and the program would set a boolean variable called is_even to True. If the remainder was not 0, the number was odd and the program would set is_even to False. The code looked like this:
# Program to determine if a number is even or odd
# Author: Alex
# Date: 2/25/2023
number = int(input("Enter a number: "))
is_even = number % 2 == 0
if is_even:
print(number, "is even")
else:
print(number, "is odd")
In this code, Alex used the modulus operator % to calculate the remainder when the number was divided by 2. They then used a comparison operator == to check if the remainder was 0. The result of this comparison was assigned to the is_even variable, which was either True or False depending on whether the number was even or odd.
As Alex continued to explore Python booleans, they discovered that they could use them in many different ways. They could use them in conditional statements like if and while to control the flow of their program. They could also use them in boolean expressions to create more complex conditions. For example, they built a program that checked if a number was between two other numbers. The code looked like this:
# Program to check if a number is between two other numbers
# Author: Alex
# Date: 2/25/2023
number = int(input("Enter a number: "))
lower_bound = 10
upper_bound = 20
is_between = lower_bound <= number <= upper_bound
if is_between:
print(number, "is between", lower_bound, "and", upper_bound)
else:
print(number, "is not between", lower_bound, "and", upper_bound)
In this code, Alex used the comparison operators <= and <= to check if the number was between the lower and upper bounds. They then used a boolean expression to combine these two conditions into a single boolean value, which was assigned to the is_between variable.
As Alex’s programming skills continued to grow, they discovered that Python booleans were an essential tool for building complex programs. They learned how to use them in conditional statements and boolean expressions to create dynamic logic. And with each new discovery, Alex became more confident in their programming abilities. They knew that with Python’s powerful boolean operations at their fingertips, they could tackle any programming task that came their way. And they all lived happily ever after.
