Pandas DataFrame column naming conventions : <p>Is there any commonly used Pandas DataFrame column naming convention? Is <a href="https://www.python.org/dev/peps/pep-0008/" rel="noreferrer">PEP8</a> recommended here (ex. instance variables)? </p>

<p>Concious that lots of data is loaded from external sources with headers but I'm curious what is the correct approach when I have to name/rename the columns on my own?</p>
