The if statement runs code only when a condition is true: python age = 18 if age >= 18: print("You can vote") The structure: if keyword, condition, colon, then indented code. The indented block only runs if the condition evaluates to True.
If age is 15, the print never runs. The program skips it and continues after the if block. If age is 18 or higher, the print executes. That's the power of conditionals: selective execution based on runtime values.
