Go up script/menu(a goto command)

[foxtreat]

i know there is not a goto or similar command in python,im trying to make a menu with submenus
a main menu that gives you games/math/managment options,and when you choose one of them it brings you to another menu where you can run a task
however i want there to be a option in the submenus that allows you to go back to main menu ,and/or after the task is finished for it to go back to its mother submenu
here is the basic code

#!/usr/bin/python
print ("\n" * 200)
print ("Welcome,what would you like to do?type the number")
print ("\n")
print ("[1]:Math solver")
print ("[2]:exit")
print ("\n")
menu = input(": ")
if menu = 1
  print ("\n" * 200)
  print ("What type is your question?")
  print ("\n" * 3)
  print ("[1]:Bisquared-equasion")
  print ("[2]:Exit")
  print ("\n")
  menu = input(": ")
  if menu = 1

if menu = 1 should run a task after which it should go back to the Math solver menu instead of quiting
how do i do that,im Really new so i need guidance and examples :(

Well, generally this would all be in a loop that would go until you got a 2 (exit). Then you could have a sub-loop for sub-menus.

I would suggest having each menu loop in it's own function, that returns when the loop is over. Then you would have something like:

if menu == 1:
    math_menu()

It help organize your code.

It would be beneficial to read this thread https://python-forum.io/Thread-Is-there-...s-in-BASIC

how will that look in my code,i have just started learning and can't get where/how to use the "math_menu()" part
i just need to see it in my code as i know what does what there,i tried reading that thread but i don't understand how to apply that to my script,thanks in advance ,and sorry for being inexperienced and dumb.not good at understanding others code

If change my code a little in link that metulburr post.
You see that it fit this kind of task well.

def solve():
   answer = int(input('What is 2 + 2? '))
   if answer == 4:
       print('\nCorrect')
   else:
       print('\nWrong')
   input('Push enter to retun to menu')

def menu():
   while True:
       print('(1) Solve something')
       print('(Q) Quit')
       choice = input('Enter your choice: ').lower()
       if choice == '1':
           solve()
       elif choice == 'q':
           return
       else:
           print('Not a correct choice: <{}>,try again'.format(choice))

if __name__ == '__main__':
  menu()

Certainly its me again and im EXTREMELY sorry for bothering so much but it gives me this error

Error:
  File "foxware 2.0.py", line 3
    def math_menu()
                  ^
SyntaxError: invalid syntax

am i supposed to paste the whole code in the brackets() or have i done something wrong elsewhere
this time im posting my whole code incase its because of a mistake elsewhere

im really sorry again.

You missed the colon at the end of the line.
