How Can I Fix Python Indentation Problems Using reindent.py?

Fixing Python Indentation Inconsistencies with reindent.py

Inconsistent indentation, a mixture of tabs and spaces, can make Python code difficult to maintain. To address this issue, Python provides the reindent.py script, located in the Tools/scripts/ directory of your Python installation.

Using reindent.py

To use reindent.py, navigate to the directory containing your Python code. Open a terminal window and run the following command:

python Tools/scripts/reindent.py <file_name>.py</file_name>

For example, to reformat the file "example.py":

python Tools/scripts/reindent.py example.py

reindent.py will automatically convert the file to use 4-space indents, remove hard tab characters, and trim excess spaces and tabs from line ends. It will also remove empty lines at the end of the file and ensure the last line ends with a newline.

Installing reindent.py

If your Linux distribution does not have reindent installed by default, you can easily install it using pip:

pip install reindent

Once installed, you can use reindent.py as described above.
