In this example, we will see how functions work. In this case we will see how the parameter passing and the return value work. Please pay attention because functions are very important but sometimes hard to understand. Can you understand the difference between printing and returning a value after this example?
| 1 | def calculate_area(width, height): |
| 2 | print("Dimensions are:", width, height) |
| 3 | result = width * height |
| 4 | return height |
| 5 | |
| 6 | def main(): |
| 7 | side1 = 12 |
| 8 | side2 = 10 |
| 9 | area = calculate_area(side1, side2) |
| 10 | print("Area is:", area) |
| 11 | print("Area is:", calculate_area(2+3, 7+2)) |
| 12 | |
| 13 | main() |
