Hej there, newbie question: I struggle to understand what exactly those two subsequent for loops in the program below do (Python 3.3.0):
for x in range(2, 10): for y in range(2, x): if x % y == 0: print(x, "equals", y, "*", x//y) break else: print(x, "is a prime number") The result is: >>> 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 I have a very basic understanding of for loops, so for example: for everything in range(10): print(everything) ... the for loop grabs everything in that given range and prints it. But I feel confused by the double use of for loops as show above. Can anyone explain?
