Imported module fails to import sub-module

Question

I have the following folder-structure

premier_league/
 |_cli_stats/
 |__ __init__.py
 |__cli_stats.py
 |__get_data/
 |__get_stats.py
 |__get_id.py
 |__api_scraper/
 |__api_scraper.py

In cli_stats.py I have the following import:

from get_data.get_stats import SeasonStats

In get_stats.py I have the following import:

from api_scraper.api_scraper import Football.

When running python cli_stats.py from the cli_stats folder the following error occurs.

 File "cli_stats.py", line 36, in <module>
 from get_data.get_stats import SeasonStats
 File "/Users/name/Desktop/Projekt/premier_league_api/cli_stats/get_data/get_stats.py", line 12, in <module>
 from api_scraper.api_scraper import Football
ModuleNotFoundError: No module named 'api_scraper'

But when running python get_stats.py from the get_data folder, the import is successful. Why does the import not work when running cli_stats.py from the cli_stats folder?

Answer 1

You have to adjust the import to a relativ one. From theget_stats.pyyou have to step into the directory. The error is that from api_scraper.api_scraper import Football is an absolut import.

Try: in get_stats.py

from .api_scraper.api_scraper import Football

(1 dot before the api_scraper)

• MisterButter: Thank you for taking your time, that solved the problem. Could you perhaps point me to any resource where where when to use relative/absolut imports are explained? Thank you for the help!
• Luc: I would recommend the official site: docs.python.org/3/reference/import.html
• Luc: Otherwise this might be helpfull: realpython.com/absolute-vs-relative-python-imports
• MisterButter: Thank you for taking your time to provide the resources, highly appreciated!
