Introduction

This manual will only work if you know Python. If you don't, go learn it at: Getting Started With Python Programming.

Program Example 1

Print all two digit positive integers $x$ such that $5x$ 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!
