While loop to run a boolean test

[vicson]

Sorry, item 2 in my list is not correct, please ignore it. I didn't see that you have return True at the end of your function.
As to item 1 - just add a line, in the while body, that changes result after user input

Hi, I have added a line that changes the result. However I still face the same problem can't exit the while loop..

    result = isValidStudentIDFormat(stid) 
    while (result != True):
        print("Invalid student id format. Please check and enter again.")
        stid = input("Enter student id: ")
        result == True

sorry I don't get it. Isn't result a variable for isValidStudentIDFormat? Aren't they the same thing?
sorry I am a newbie to programming...
