How Do I Resolve Python Import Errors Caused by Duplicate Local File Names?

Using Imported Libraries with Duplicate Local File Names

Error Description

When importing a library from a file with the same name as the imported library, you may encounter errors such as AttributeError, ImportError, or NameError.

Resolution

The issue arises due to name collisions. Python pre-appends the current directory to its search path (sys.path), causing your local requests.py file to take precedence over the installed requests module.

Solution

To resolve this issue:

1. Rename your local script to avoid name collision.
2. If a requests.pyc file persists, remove it as it can still interfere.

Enhanced Debugging Techniques

1. Inspect the Traceback Carefully: Confirm that the name of your script matches the module you are importing.
2. Check for Nested Collisions: Ensure that the name of your file does not match a module imported by any other included module.

Note

This issue is not limited to exact module name matches. It can also occur when your local file's name matches a module imported by a dependency. To avoid such errors, follow these guidelines:

1. Choose unique module names whenever possible.
2. Adjust module names when encountering import errors related to duplicate names.
