while loop

How can the while loop be written better in the code snippet below, or do you think there is an error? #code requirements: #if character is not letter, it is requested to enter text consisting of letters again T = True while T: text = input("enter a text consisting of only letters: ") for i in text: if not i.isalpha(): text = input("enter a text consisting of only letters: ") break else: T = False

No extra loop required here: while True: text = input("Enter a text consisting of only letters.\n") if text.isalpha(): print("Your input:",text); break else: print("You entered a number. ")

Bekir your posted code would prompt for input three times if a non-alpha char gets entered once at the first prompt. Input from the second prompt would be ignored. Here is a correction: T = True while T: text = input("enter a text consisting of only letters: ") for i in text: T = not i.isalpha() if T: break

Thanks Brain. Yes, I saw the error you mentioned. But I don't understand my code error. But I'm trying to understand. Also your code is really good.
