You can create nested loops in python fairly easily. You can even nest a for loop inside a while loop or the other way around. For example,
for i in range(5): j = i while j != 0: print(j, end=', ') j -= 1 print("")
This will give the output
1, 2, 1, 3, 2, 1, 4, 3, 2, 1,
You can take this nesting to as many levels as you like.
