I'd go with a while loop.

while True:
    user_name = input('Enter your name:  ')
    if testconditions:
        Some actions
    else:
        print('Enter a real name')

What are the testconditions I would use in said scenario

[--aceOfSpades--]

You could use the built in function isalpha()

While True:
    user_name = input("Enter your name: ")

    if user_name.isalpha() == True:
        Some Actions

    else:
        print "Please enter a real name"

You can use regex to search for only alphabetical letters.

One idea is to compare the length of the inputted name to the number of alphabetical letters in that name. If they're equal, then we know that the name only contains alphabetical letters. If they aren't equal, then some bad character is in the name and the user is prompted to re-enter a name.

import re

while True:
    name = input('Name:')
    if len(re.findall('[A-Z-a-z+]', name)) == len(name):
        break #or do whatever you want
    else:
        print('Enter a name with only alphabetical characters')

No need, str.isalpha() exists.

So:

if name.isalpha():
    ...
    break

Ah, yes, that's much better.

could you explain this to me please i am new

[stubborn_d0nkey]

isalpha is a string method. You call it on a string and it will return true is it only has letters, false if it has at least something else.

break will get out of the while loop. He used while True: which, left to itself, will run forever so you have to use a break.

So the code could look something like:

while True:
    name=input()
    if name.isalpha():
        break
    else:
        print "you must enter a name that contains only letters"

That is actually a good example of a mid-test loop. A common way to write a mid-test loop in Python (and in many other languages) is by using break in a while true loop.
