Can't drop NAN with dropna in pandas

Question

I import pandas as pd and run the code below and get the following result

Code:

traindataset = pd.read_csv(\'/Users/train.csv\')
print traindataset.d         


        

Answer 1

You need to read the documentation (emphasis added):

Return object with labels on given axis omitted

dropna returns a new DataFrame. If you want it to modify the existing DataFrame, all you have to do is read further in the documentation:

inplace : boolean, default False

If True, do operation inplace and return None.

So to modify it in place, do traindataset.dropna(how='any', inplace=True).
