you can set the base path as follows
import os
from pathlib import Path
# Make sure in source path:
os.chdir(os.path.abspath(os.path.dirname(__file__)))
homepath = Path('.')
onebelow = homepath / 'onebelowname'
# Also, if you want path created if it doesn't already exist then add
onebelow.mkdir(exist_ok=True)
# to create a file in that directory:
mynewfile = onebelow / 'mynewfilename'
# To open that file for writing text
with mynewfile.open('w') as fp:
fp.write('whatever')
