"continue" and "else" are completely unrelated. "continue" can only be inside a for-loop or a while-loop, and it immediately jumps back to the beginning of the next loop. If I write this: for i in range(10): print(i) continue print("This will never be printed") it will print the numbers 0 through 9 but never reach the second print. Obviously, unconditionally using "continue" in this way is silly. If you don't ever want the second print line, why not just leave it out? But it is useful to conditionally continue or not, which means you will nearly always see "continue" somewhere inside an if...elif...else block. For example: for i in range(20): if i%2 == 0: print("Skipping an even number") continue print("Odd number {}".format(i)) print("Remainder when divided by three is: {}".format(i%3)) The continue need not be inside the "if" block. It could be inside an "elif" or "else" block instead. -- Steven _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
