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

Make sure you've the module pycodestyle or flake8 to be able to check your code against the style guides. Then enable the magic function by using the pycodestyle_magic module (github repo):

pip install flake8 pycodestyle_magic

• first load the magic in a Jupyter Notebook cell:

%load_ext pycodestyle_magic

• and then turn on the magic to do compliance checking for each cell using:

%pycodestyle_on or %flake8_on

depending against which style guide you want to check.

To turn off the auto-compliance-checking run:

%pycodestyle_off or %flake8_off
