It doesn't run because you have a try without a matching except

There 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:).
