Reformatting Source Code
PyCharm lets you reformat source code to meet the requirements of your code style. PyCharm will lay out spacing, indents, keywords etc. Reformatting can apply to the selected text, entire file, or entire project.
It is also possible to apply reformatting to the parts of the source code only, using the formatting markers.

Skipping a region when reformatting source code
To enable formatter markers, make sure to select the checkbox Enable formatter markers in comments in the Markers page of the Settings/Preferences dialog, and type the markers in the Formatter off/on fields.
To skip a certain region on reformatting, follow these steps:
At the beginning of the region, create a line comment (Ctrl+/), and then manually type the marker specified in the Formatter off field of Code Style page.
At the end of the region, create a line comment (Ctrl+/), and then manually type the marker specified in the Formatter on field of Code Style page.
Perform code reformatting, as described above.
