As an aside, you should change the above line to:
for line in fh:
"readlines()" will read the entire file into memory at once, while just
iterating through it won't, so you'll save memory on large files.

This is very trivial, but you could change the above line to:
result = "\t".join(id, gene_symbol, ptms)
