I need to use this function to validate my input in the below code:
How can I make that function call in the below code.
I need to validate the ID captured as in the below code and only then the next input() i.e doctor will be captured.

import datetime
from datetime import datetime
n = 5
while n > 0:
    id = input("Please enter your ID: ")
    with open("C:\\Users\\ABCD\\EFG\\" "%s.txt" % id, "a") as file:
        ID = input("Please provide your ID: ")
        Doctor = input("Please provide the name of the doctor you would like to visit: ")

Thanks

def check_input():
    while True:
        id = input("Please enter your ID: ")
        if len(id) == 8:
            print("Thanks for the input ", id)
            return id
        else:
            print(id, " does not contain 8 alphanumeric characters, please enter your ID again")

id = check_input()
