Recalling function (recursion) versus using while statement in Python

Well, I know that you can run the program as long as a certain condition is true using the while statement . However, is it wrong or bad practice to just call a function in else , as shown below?

def ask():
    me = input("What is your name? ")

    if me == "Tom":
        print("Hi, Tom!")
    else:
        print ("Who are you?")
        ask()

This seems like a lighter, shorter version of the “while statement”, but in fact I have not seen a program like this in Python tutorials.

ask while, . 'while' 'for', return.
