ALL functions need a formatted docstring – see the bottom of Mod 3 Lesson 1 Activity for the requirements. Module Seven Lesson Three Activity Two View range(stop) video The range( stop ) function creates a sequence Using 1 argument with range( stop ): Default start: 0 stop: stopping integer, does not process stop number for count in range(10): print(count) Same as for count in [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]: print(count) Concept: range(stop) Examples: Range runs from 0 through the integer before stop # [ ] review and run example for count in range(10): print(count) 0 1 2 3 4 5 6 7 8 9
