Answer 1

You can use pathlib library.

from pathlib import Path
ap= open(f"{Path(fname).stem}ws.csv",'a')

It will save second csv with "15ws.csv" filename

See this question:

Try this:

import os

fname = r"15.csv"

name, ext = os.path.splitext(fname)
ap = open(f"{name}ws{ext}", 'a') 
ap.write(" "+r) 
ap.close()
