How to check that user has entered the value which is listed in python list eg [1,2,3,4,5]

Question

Eg.

Mylist = [1,2,3,4,5]

User_ip = 3

#user enters a value that is in the python list and if not print- not in the list

I am trying it with for loop but logic not works

for i in Mylist:
    if i== User_ip:
        print ("value is in the list")
    else:
        print ("value not in the list")

If you do as @quamrana suggested, you also don't need the `for` loop — Cory Kramer, May 17 '21 at 19:33

Why not just check :

if User_ip in Mylist:
    print ("value is in the list")
else:
    print ("value not in the list")

You can check if a item is in the list with the in Operator:

Mylist = [1,2,3,4,5]

User_ip = 3

if User_ip in Mylist:
    print("value is in the list")
else:
    print("value not in the list")

While code-only answers might answer the question, you could significantly improve the quality of your answer by providing context for your code, a reason for why this code works, and some references to documentation for further reading.
