Import Error partially initialized from imported file-CodePudding

i dont know how i can call function from the file who import.

toolkit.py:

from utilities import bcolors, utility
from backups import backups
import os
version = "1.0"

utility.UpdateNeeded()

class main():
    def main():
        print( bcolors.BOLD   "Toolkit"   bcolors.ENDC)

        print("")
        choose = int(input(bcolors.BOLD   "1"    ": "   bcolors.CYELLOW   "Backups"   bcolors.ENDC   "\n\
" bcolors.BOLD   "0"    ": "   bcolors.CYELLOW   "Close"   bcolors.ENDC   "\n\
> "))
        if choose == 0:
            #exit
            print(bcolors.CGREEN   "Ciao."   bcolors.ENDC)
            exit()
        if choose == 1:
            #do magic
            os.system('cls')
            main.menu_backup()

    def menu_backup():
        choose = int(input(bcolors.BOLD   "1"    ": "   bcolors.CYELLOW   "Check Backups"   bcolors.ENDC   "\n\
" bcolors.BOLD   "0"    ": "   bcolors.CYELLOW   "Main Menu"   bcolors.ENDC   "\n\
> "))
        if choose == 0:
            os.system('cls')
            main.main()
        if choose == 1:
            os.system('cls')
            backups.check_backups()

main.main()

backups.py:

from utilities import bcolors, utility
from toolkit import main


class backups:
    def __init__(self, my_dirs, my_files,           
                     curdir): 
        self.my_dirs = [] 
        self.my_files = [] 
        self.curdir = '' 

    def check_backups(ln):
        print(bcolors.CRED   "Check Backups..."   bcolors.ENDC)
        main.menu_backup()

utilities.py:

class bcolors:
    ENDC = '\033[0m'
    BOLD = '\033[1m'
    CRED    = '\33[31m'
    CGREEN  = '\33[32m'
    CYELLOW = '\33[33m'

class utility:
    #def __init__(self):
    
    def UpdateNeeded():
        print("update check...")

that gives me following error:

ImportError: cannot import name 'backups' from partially initialized module 'backups' (most likely due to a circular import)

CodePudding user response：

In toolkit.py you are trying to import something from backups.py, but in backups.py you are trying to import something from toolkit.py. Python can't import the one without the other so it goes into a loop, detects it and gives you this error. You need to separate the two components so that they are not dependent on each other anymore.
