Dictionary RUNTIME problem at python hackerrank question (noob question)

All test cases done except for one and that one had Runtime error.. I am not one-liner, because i am beginner.. Is there any solution for my level?

Here is my code:

n = int(input())
phonelist = dict()
for i in range(n):
    user = input().strip().split()
    phonelist[user[0]] = user[1]    
for i in range(n):
    ask = str(input())
    if ask in phonelist:
        print(f"{ask}={phonelist[ask]}")
    else:
        print("Not found") #RUNTIME Error at case 1

Problem Statement : HERE

The number of queries is not fixed, as mentioned in italics in the problem statement as well, so you need to keep reading until you encounter EOF:

while True:
    try:
        ask = input()
        if ask in phonelist:
            print(f"{ask}={phonelist[ask]}")
        else:
            print("Not found") #RUNTIME Error at case 1
    except: # break when exception in reading EOF
        break

See accepted submission of this code.
