Boolean Values

In programming, you often need to know if an expression is True or False. Boolean values are the foundation of logical operations and decision-making in programming.

In Python, there are two Boolean values:

• True
• False

Evaluating Expressions

You can evaluate any expression in Python and get one of two answers: True or False. For example:

        # Example of Boolean expressions
        x = 10
        y = 5
        print(x > y)  # Output: True
        print(x < y)  # Output: False
     

Boolean Operations

Python supports several Boolean operations that can be used to combine Boolean values:

• AND: Returns True if both statements are true.
• OR: Returns True if at least one of the statements is true.
• NOT: Reverses the result, returns False if the result is true.

Examples:

        # Example of Boolean operations
        a = True
        b = False
        
        print(a and b)  # Output: False
        print(a or b)   # Output: True
        print(not a)    # Output: False
     

Common Use Cases

Boolean values are commonly used in conditional statements, such as:

        # Using Boolean values in an if statement
        is_raining = False
        
        if is_raining:
            print("Take an umbrella.")
        else:
            print("Enjoy your day!")
     

Conclusion

Understanding Boolean values and operations is essential for control flow in Python programming. They allow for the creation of more complex logic in applications.
