Getting program to run multiple times
-
I am doing some calculation work and I have something that works, but I am having trouble making it run multiple times. I would like to run a bunch of different values but at the moment it only runs once in the console and kicks you out. How can I change this to run until the user stops the program. Thanks for any help
import math def main(): try: bump=float(input('\nbump height? ')) tire=float(input('tire diameter in inches? ')) speed=float(input('vehicle speed in miles per hour? ')) except ValueError: print('\nyou entered an invalid input') else: print('the hub speed is ' + repr(round((calculatehubspeed(bump, tire, speed)))) + ' inches per second') def calculatehubspeed(bump, tire, speed): answer = bump/(math.sqrt((tire/2)**2-((tire/2-bump)**2))/(speed*17.6)) return(answer) if __name__ == '__main__': main() ```

It should be enough to put your entire main code into a
while True
loop. That way it will repeat forever (until you press the stop button - that raises an exception, which stops the loop). -
Put main() into a while True or for x in range() loop.
#your definitions and so on... While True: main() #the indented part is now repeating for eternity... :-) if you wish to stop the loop, just insert the command break
The for x in range(range) loop will repeat for x times whatever integer the range variable is set to.
for x in range(12): print(x) # x is equal to the number of times that the loop has been executed already main() # now your code is repeated 12 times

Thanks for helping me. It took about 10 seconds to change it after I read about the While loop. I was tying to put the main function in the loop, which was wrong. I needed to put the main function call in the While loop.
I have a bunch of calculations for use in the console but I want to put them into some kind of menu and page (with textboxes for answers) app so there can be a number keypad for ease of useAgain, this forum never lets me down, Thanks guys and gals
