It doesn't run because you have a
try without a matching exceptThere are a few issues with your code for starters:
again is assigned as 'y' and never re-assigned so the first while loop will always be True.The second while loop is not required.
key is repeatedly assigned on every while loop iteration and is never used.A file is opened and never closed
ans is not defined

You don't need three while loops; one loop for entering the student name and file, one loop for reading the file. Actually, I would make the inner loop a for loop.
for line in file:It is much easier using the file iterator than using readline().
You should close you file when you are done with it. Either use file.close() or use a context manager (with open(filename, "r") as file:).
