python - Verifying PEP8 in iPython notebook code

Question

Is there an easy way to check that iPython notebook code, while it's being written, is compliant with PEP8?

Answer 1

In case this helps anyone, I'm using:

conttest "jupyter nbconvert notebook.ipynb --stdout --to script | flake8 - --ignore=W391"

• conttest reruns when saving changes to the notebook
• flake8 - tells flake8 to take input from stdin
• --ignore=W391 - this is because the output of jupyter nbconvert seems to always have a "blank line at end of file", so I don't want flake8 to complain about that.

I'm having a problem with markdown cells (whose line lengths may legitimately be quite long, though): ignore markdown cells in `jupyter nbconvert` with `--to script`.
