EOF error

Question

So, with what I've learned to this point (up to else statements), I tried to write this code:
x = int(input("complete this problem:1+1+1+1=..."))
if x==4:
print("correct")
else:
print("incorrect")
print("try again")
x = int(input("complete this problem: 1+1+1+1=..."))
if x==4:
print("FINALLY! CORRECT!")
else:
print("wrong again")
I am getting an EOF error at line 7. Can anyone advise how to fix this and explain what I did wrong? thanks.

Answer 1

u can do it easier with a loop it will repeat till the user enters 4
x = 0
while x != 4:
x = int(input("Complete -> 1+1+1+1=..."))
if x == 4:
print("correct")
else:
print("Incorrect")
print("Try Again")

Answer 2

the Code i posted will do that

Answer 3

if I END the code at line 7 it works, but the code needs to be rerun again...and again...until the correct answer is entered.
is there a way change this code to continue to prompt the user for input until the correct answer is entered?
again, there is an EOF error line 7.
