 A list of files to check Returns: bool: **True** if all files passed the checks, **False** otherwise. pep8 tool is **very** fast. Especially compared to pylint and the bigger the code base the bigger the difference. If you want to reduce check times you might disable all pep8 checks in pylint and use pep8 for that. This way you use pylint only for the more advanced checks (the number of checks enabled in pylint will make a visible difference in it's run times). """
