file - python menu Game menu game... etc -

i'm making game in python using pygame , other libraries. have main menu 1 python file, , when player selected, starts game file. if choose go menu while playing game, starts menu again. new menu can't start/open game file anymore doesn't @ all. (after each time open file close previous one)

eg:

menu-->playerselect-->gamestartup-->menu-->playerselect-->break/crash.

so actual code first file menu name "flappybirdmain, "happybrid" name of second game file.

if startgui == 2:     screen.blit(background, [0, 0])     import happybird      done=true     pygame.quit() 

for second file "happybird" have open menu connected pressing down "m" key:

            if event.key == k_m:                 pygame.mixer.fadeout(1)                 import flappybirdmain                 done=true 

so import flappybirdmain done=true closes "happybird" file

i have figured out making copies of same files("flappybirdmain", , "happybird") making them import each other in series can have menu come go down again(more once) when link origonal file crash/breaks eg:

ex1:

flappybirdmain-->happybird-->flappybirdmain2-->happybird2-->flappybirdmain3-->happybird3

ex2:

flappybirdmain-->happybird-->flappybirdmain2-->happybird2-->flappybirdmain3-->happybird3-->flappybirdmain

the problem using import command. exec(open("happybird.py").read())

using import cuases python think open, smart import system. (or along lines of that).

repeating import module - python / pygame

^the link how figured out.

thanks.

using import start menu not solution.

if have menu.py

print("hello world") 

it works when import first time in game.py

import menu 

but can put in function

def run_it():     print("hello world") 

and can use many times

import menu  menu.run_it()  # , again  menu.run_it()  # , again  menu.run_it() 

if use class

class menu():     def update():        pass     def draw():        pass     def event_handler():        pass     def mainloop():        print("hello world") 

then can run many times too

menu = menu()  menu.mainloop()  # , again  menu.mainloop()  # , again  menu.mainloop()
