How do I say, if variable = any integer, in Python 2x

Question

import random 

print ("hello")

user_friend1 = raw_input("Name one of your friends: ")

user_friend2 = raw_input("Name another friend: ")
# inputs for user
friends = [user_friend1,user_friend2] 

best_friend = random.sample(friends, 1)

I want to loop it so that if a user types an integer to a question then it will ask the question again, i need it for both questions user_friend 1 and 2

print ("your best friend is %s") % (best_friend)

`isinstance(variable, int)` would be more pythonic, no? @JoshuaNixon — James R, Mar 15 '17 at 20:35
@JamesR not going to lie I've never seen that. yes it would be better. Going to have to change my computing coursework now! — Joshua Nixon, Mar 15 '17 at 20:41

if type(variable) == int:

This gets the type of the variable and compares it to the class int

You should use isinstance()

if isinstance(variable, int):
    do_something()

Use this

import random
while True:
    friend1 = raw_input("Name one of your friends: ")
    try:
        val = int(friend1)
    except ValueError:
        break
    print("Enter valid name")
while True:
    friend2 = raw_input("Name another friend: ")
    try:
        val = int(friend2)
    except ValueError:
        break
    print("Enter valid name")
friends = [friend1,friend2]
best_friend = random.sample(friends, 1)
print("your bestfriend is %s" %(best_friend))

Output

Name one of your friends: 1
Enter valid name

Name one of your friends: 1
Enter valid name

Name one of your friends: tilak

Name another friend: varma
your bestfriend is ['varma']

I want to ask the question twice, what would I do then? type it in twice? – Siddharth Chaudhary Mar 15 '17 at 20:46
see the complete solution to your work as i edited it now – Tilak Putta Mar 15 '17 at 21:08
it's saying that my best friend is 1 (the integer I inputted)? – Siddharth Chaudhary Mar 15 '17 at 21:09
see the ouput that i edited , it does show the input numbers – Tilak Putta Mar 15 '17 at 21:12
what do you mean by 'val'? – Siddharth Chaudhary Mar 15 '17 at 21:12
just copy this code into your code and execute it .. val is just a variable that will be initialised if given is integer – Tilak Putta Mar 15 '17 at 21:13
did you get this now, upvote and accept my answer if you do. – Tilak Putta Mar 15 '17 at 21:14
