[Tutor] Range within a range

[Andoni Gorostiza]

Hi tutor. I need your help with something I don't understand. In the tutorial, it mentions an example of a range within a range. I'll keep it simplified. How exactly does this work? I'll provide a few examples.

>>> for x in range(0,5):
...for n in range(0,5):
...          print(x)

>>> for x in range(0,5):
...for n in range(0,5)
...          print(n)

This one comes from the tutorial:

>>> for n in range(2, 10): ...  for x in range(2, n): ...  if n % x == 0: ...  print(n, 'equals', x, '*', n//x) ...  break ...  else: ...  # loop fell through without finding a factor ...  print(n, 'is a prime number') ... 2 is a prime number 3 is a prime number 4 equals 2 * 2 5 is a prime number 6 equals 2 * 3 7 is a prime number 8 equals 2 * 4 9 equals 3 * 3 
Can you explain what is going on?
