A package for PEP8 analysis in browser based Jupyter notebooks, such as Kaggle and Google Colabatory, that do not allow adding 3rd Party PEP8 analysis tools as add ons.

• Install pycodestyle if already not installed. This package replaces old pep8 package. It comes pre-installed in Kaggle notebooks but not in Google Colabs.
• Install nbpep8 from test.pypi . I will push to PyPI in future.

pip install pycodestyle
pip install --index-url https://test.pypi.org/simple/ nbpep8

from nbpep8.nbpep8 import pep8

Add pep8(_ih) at the end of the code cell to see PEP8 analysis.

Example:

import os,sys
a =  23

pep8(_ih)

Output:

cell_content.py:1:10: E231 missing whitespace after ','
cell_content.py:1:10: E401 multiple imports on one line
cell_content.py:2:4: E222 multiple spaces after operator
