how to make input variable with only the alphabet

Question

This is the problem I am facing. Can anyone help

name=input("What is your name?")
name= input.lower()

when it runs this is what comes up

What is your name?Bob

Traceback (most recent call last):
  File "E:\eval task 1 GCSE.py", line 6, in <module>
    name= input.lower()
AttributeError: 'builtin_function_or_method' object has no attribute 'lower'

can anyone fix this please. I need to make sure that I can only enter letters from the alphabet for my name input. Can anyone show me how to do this. Very appreciated

You get the user input with the `input` function, then store it in a variable `name`. You then try to call the `lower` method of the `input` function which doesn't exist. Change `input.lower()` to `name.lower()`. — Colonel Thirty Two, Oct 13 '15 at 21:56
Your intention isn't completely clear. Do you need to reject the input outright if it contains numeric characters? Or do you want to keep the input but merely filter the non-alphabetic characters? — foundling, Oct 13 '15 at 22:15
Basically I want make a variable called name which only accepts letter from the alphabet. If they input an integer instead then I want it to stop and print this I not a valid name — GamingKing720, Oct 13 '15 at 22:18

Ryan can you help me out here. Now that it this works I was wondering how I could make validation so that if they enter an integer I can say that is invalid. Any thoughts – GamingKing720 Oct 13 '15 at 22:06
Doing homework? ;-) Read this: https://docs.python.org/2/library/stdtypes.html#string-methods – tenwest Oct 13 '15 at 22:08
for example, if you don't want them entering numbers at all in their name, name.isalpha should be true, if its false--then there's a number there (or other non-alphabetic character) – tenwest Oct 13 '15 at 22:10
I don't understand the str isalpha – GamingKing720 Oct 13 '15 at 22:11

Try this:

username=input("What is your name?").lower()
for char in username:
    if not char.isalpha():
        print "invalid username"
        break
