Pandas Mean - Get Average | pd.DataFrame.mean()

You're anything but average! Jokes aside, Pandas Mean is a fundamental function that is in very data scientist, analyst, and data monkey around.

Pandas Mean will return the average of your data across a specified axis. If the function is applied to a DataFrame, pandas will return a series with the mean across an axis. If .mean() is applied to a Series, then pandas will return a scalar (single number).
