Return percentage of Null values in pd.Series.isnull()
See original GitHub issueProblem description
One thing I have to check a lot at my work is the percentage of null values in a DataFrame column. What I end up doing is
(df[column].isnull().sum() * 100/ len(df)).sort_values(ascending=False)
I think it would be very convenient to have a parameter, like:
df[column].isnull(ratio=True,sort=True)
What do you guys think?
