It’s common for PyCharm’s code analysis to get out of sync with how Python actually runs your script, even when everything works at execution time. Here are a few straightforward ways to eliminate those red lines:

Solution 1: Use the Proper Relative Import (Recommended) #

The cleanest approach is to adjust your import statement to match your project’s actual package structure. In test.py, replace:

from module import func1

with:

from package.module import func1

This follows standard Python packaging conventions, and PyCharm will immediately recognize the path once you make the change—no extra setup needed.

Solution 2: Mark the package Directory as a Sources Root #

If you want to keep your original import statement, tell PyCharm to treat the package folder as a source directory (so it looks there for modules):

• Right-click on the package folder in PyCharm’s Project sidebar
• Hover over Mark Directory as
• Select Sources Root
  The folder will turn blue, and PyCharm will stop flagging module and func1 as unresolved references.

Solution 3: Add the package Directory to Your Interpreter’s Path #

Another option is to manually add the package folder to PyCharm’s list of paths for your Python interpreter:

1. Go to File > Settings > Project: [Your Project Name] > Python Interpreter
2. Click the gear icon next to your interpreter, then select Show All
3. Choose your active interpreter, then click the folder-with-arrow icon labeled Show paths for the selected interpreter
4. Click the + button, navigate to your project’s package directory, and add it
5. Save your changes by clicking OK in all open windows. PyCharm will now include this directory when resolving imports.

Even though your script runs fine now, using Solution 1 is the best practice—it ensures your code works consistently across different environments and follows Python’s packaging rules.
