There are python files a.py and b.py. And b.py is imported in a.py by import b.
How to get the absolute path of a.py in b.py when a.py runs?

b.py
import os
import traceback
try: assert 0
except:
st = traceback.format_stack()
# format of st --> [' File "filename", line 1, in <module>\n import b\n', ... ... ]
relative_p = st[0].split(',')[0].split(' ')[-1].split('"')[1]
abs_path = os.path.abspath(relative_p)
print(abs_path)
# prints the importer's path, else if no importer, then itself's abs path
# rest of program goes here ...
