How To Write Conditional Statements in Python 3

Conditional statements are an essential component of programming, and Python 3 provides several ways to write them. In this tutorial, we'll explore the different types of conditional statements in Python 3, including if-else statements and elif statements.

The if-else Statement

The if-else statement is the most basic type of conditional statement in Python 3. It allows us to execute different blocks of code based on whether a certain condition is true or false.

      
        # Example of if-else statement
        x = 10
        if x > 5:
            print("x is greater than 5")
        else:
            print("x is less than or equal to 5")
      
    

In the above example, the code inside the if block will execute only if the condition x > 5 is true. If the condition is false, the code inside the else block will execute.

The elif Statement

The elif statement is used when we have multiple conditions to check. It stands for "else if" and allows us to check for multiple conditions in sequence. We can use as many elif statements as we need.

      
        # Example of elif statement
        x = 10
        if x > 15:
            print("x is greater than 15")
        elif x > 10:
            print("x is greater than 10")
        else:
            print("x is less than or equal to 10")
      
    

In the above example, the code inside the first elif block will execute only if the condition x > 15 is false and the condition x > 10 is true. If both conditions are false, the code inside the else block will execute.

Conclusion

Conditional statements are an essential part of programming, and Python 3 provides several ways to write them. By using if-else and elif statements, we can execute different blocks of code based on different conditions. This tutorial should give you a good starting point for writing conditional statements in Python 3.
