Question 1: The user will enter a list of numbers and a separate number. The program will display the index at which the number is present in the list. If the number is absent, it'll return -1. Do NOT use built-in functions for searching.

user_list2=input([])
for i in range(0,len(user_list2)):
    num=input()
    if num in user_list2:
        user_list2.index(num)
    else:
        print(-1)
