This worked for me but I had to replace != with 'is not', i.e.:
[e for e in list if e is not None]
otherwise I got TypeError: Could not compare [None] with block values

Better use this :

import pandas as pd
def remove_none_elements_from_list(list):
     return [e for e in list if(pd.notnull(e))]`

Why use pandas? Because it takes into account None and float("nan").

and don't use built-ins as variable names.
