python - Find index of all rows with null values in a particular column in pandas dataframe

Question

I have been worried about how to find indices of all rows with null values in a particular column of a pandas dataframe in python. If A is one of the entries in df.columns then I need to find indices of each row with null values in A

Answer 1

Supposing you need the indices as a list, one option would be:

df[df['A'].isnull()].index.tolist()
