I'm trying to figure out how to return my script back to line 1 which is basically the main menu. It is the last part I need to make sure the program runs correctly but I am new to programming and can't quite finish this last detail. I have attached the script below. Any and all help would be greatly appreciated.

print("Select the calculator you would like to use.\n") print("1. PSI Calculation 11. CU-IN/REV") print("2. Torque Force 12. CC/REV") print("3. Horsepower Applied 13. Torque Applied") print("4. Flow Rate 14. Stroke Time") print("5. Gallons Per Minute 15. Blind End Cylinder Area") print("6. Tine Shaft Bend 16. Rod End Cylinder Area") print("7. Electric Horsepower") print("8.

  • put all in a function and call that function in a while loop. Commented Oct 8, 2021 at 19:32
  • You can't. If you want to repeat code you have to create the appropriate control structures like functions and loops. Commented Oct 8, 2021 at 19:32

    When writing questions, use minimal examples that demonstrate the problem. We don't need a thousand lines of code when a few will do. Commented Oct 8, 2021 at 19:34
  • you don't need to import os in each if statement, do it once at the start of the file and the third float around everything is redundant: float(float(Flow) * float(Restriction)) Commented Oct 8, 2021 at 19:35
