Got it, let's break down why this is happening and get it fixed. When you run python ./code/prog.py from your project_folder in the terminal, Python automatically adds your current working directory to its module search path — that's why import funs works. But PyCharm's interactive console isn't using the same setup by default, which leads to the import error.

Here are the most straightforward fixes, ordered from permanent to quick-and-dirty:

1. Mark Your Project Root as a Sources Root #

This is the most reliable permanent fix:

• In PyCharm's Project sidebar, right-click on your project_folder.
• Hover over Mark Directory as and select Sources Root. This tells PyCharm to treat this folder as a top-level module directory, so it'll recognize the code subfolder and its contents.
• Restart the interactive console after doing this — the import should start working.

2. Adjust the Console's Working Directory #

If marking the sources root doesn't do the trick, check where the console is running from:

• Go to Run > Edit Configurations...
• In the left pane, find and select Python Console (the configuration for the interactive console).
• In the right pane, look for the Working directory field. Make sure it's set to the absolute path of your project_folder, not the code subfolder.
• Click Apply and OK, then restart the console.

3. Quick Temporary Workaround #

If you need to get the import working right away without changing settings, manually add the project path to Python's search path in the console:

import sys
# Replace this with your actual project_folder path
sys.path.append("/full/path/to/your/project_folder")
import funs

This bypasses PyCharm's path settings temporarily, but you'll have to run this every time you open the console unless you fix the permanent settings above.

4. Double-Check Your Python SDK #

Sometimes the issue is that PyCharm is using a different Python environment than your terminal:

• Go to File > Project Structure > Project Settings > Project SDK.
• Make sure the selected SDK matches the Python version you're using in the terminal (run python --version in your terminal to check).
• If it's different, select the correct one from the dropdown or add it using the + button.

The key here is aligning PyCharm's module search path with what your terminal uses. Once you set the sources root and working directory correctly, the import funs command will work just like it does in the terminal.
