Unable to import a file in python

I want to import a file in a local directory but python refused to do so and it gives error everytime i do so.

I tried putting "from Admin_login import Admin_login" but it gives an error saying

"ModuleNotFoundError: No module named 'Admin_login'"

my code:-(main.py)

from .Admin_login import Admin_login

loggsin = Admin_login.login()

if loggsin == True:
    print("You are logged in")

This is the Admin_login.py file

import json
import os

def load_data():
    with open("data.json", "r") as f:
        Data = json.load(f)
    return Data

class Admin_login():
        def login(self):
            Login = False
            while Login == False:
                id = input("Enter the id you want to login = ")
                data = load_data()
                if id == data["id"]:
                    print(data["name"])
                    passord = input("Enter the password = ")
                    if passord == data["password"]:
                        print("You are successfully logged in")
                        Login = True
                        return Login
                        os.system('cls')

                else:
                    print("The id doesn't exist... Please try again!")
                    Login = False
                    return Login
                    os.system('cls')



if __name__ == '__main__' :
    Admin_login()

and the error it gives is :-

Traceback (most recent call last):
  File "C:\Users\myUser\Desktop\LibApp\main.py", line 1, in <module>
    from .Admin_login import Admin_login
ImportError: attempted relative import with no known parent package

pls help
