Python Control Flow (If Statements)

Python Control Flow (If Statements)

Control flow structures allow your program to make decisions based on conditions. The if statement is used for this purpose.

If Statements

The if statement is used to test conditions. If the condition is True, the code inside the block runs:

      
        age = 18
        if age >= 18:
            print("You are an adult.")
        else:
            print("You are a minor.")
