Question: I am using Spyder 2.3.1 and python(x, y).

In the preferences of Spyder you can activate "Style analysis".
This is quite nice, but I want to increase the max. tolerable line length. 
The standard setting for PEP8 is 79 characters.
This can be changed through a setup.cfg with the content:

```
[pep8]
max-line-length = 99

```

This can be read here: <http://pep8.readthedocs.org/en/latest/intro.html#related-tools>

*Where do I put a setup.cfg so Spyder/PEP8 will recognize my new limit?*
Or is there an other way to set this limit or to ignore E501 (line to long)?
Just setting "Show vertical line after 99 characters" in Spyder does not help.

Answer: 
If you are user "myname" using conda, in environment "myenv" try to edit the file: 
/home/myname/miniconda3/envs/myenv/lib/python3.7/site-packages/pycodestyle.py
and change MAX\_LINE\_LENGTH=79 to MAX\_LINE\_LENGTH=100, for example. 
Worked for my Spyder 3.3.6.
The tox.ini with a pep8 section or a setup.cfg at the project level should do.
