Why am I getting a syntax error on this else if statement?

Syntax error I get is invalid syntax: else: ^

import random

num = random.randint(1, 7)

def dice_roll():

gold = 0
input = ('Do you want to play again?' )
if num == 2:
    gold = (gold + 2)

    print (gold)
    print ('You Win!')
    print (input)

    if input != ('yes'):
        dice_roll()


        else:
            print ('Loser')

dice_roll()
