| − | ===Program Example 1===
| |
| − |
| |
| − | '''Print all two digit positive integers <math>x</math> such that <math>5x</math> is a three digit positive integer.'''
| |
| − |
| |
| − | We can keep our code and modify some parts of it.
| |
| − |
| |
| − | def check(a, min, max):
| |
| − | if a*5 > min - 1 and a*5 < max + 1:
| |
| − | return True
| |
| − | else:
| |
| − | return False
| |
| − |
| |
| − | def print_check(range_min, range_max, check_min, check_max):
| |
| − | for i in range(range_min, range_max + 1):
| |
| − | if check(i, check_min, check_max):
| |
| − | print(i)
| |
| − | return
| |
| − |
| |
| − | print_check(10, 99, 100, 999)
| |
| − |
| |
| − | Why did we add so many functions?
| |
| − |
| |
| − | Well, if the numbers in a problem change (and the words stay the same), and you need to change a lot of numbers in your program, your program is considered '''hard-coded'''. We want our programs to be as '''soft-coded''' as possible. In our new program, we only need to change 4 numbers (in the print_check() statement) if the numbers in the problem change. Therefore, our program is relatively soft-coded. There are still ways to soft-code this program even more, though.
| |
| − |
| |
| − | If we run our program, we get our answer.
| |
| − |
| |
| − | All numbers from 20 to 99 work!
