Python

How can I run a function from another file?
type

from main import main # импорт нужной функции

start_game = input("start game? yes/no")

if start_game == "yes":
    main()

elif start_game == "no":
    quit()

I want to make the game menu, but this method, when imported, immediately starts the file and the Main function,
and I need this file to start the main function only when I let you know about it.
