    df = pandas.DataFrame({A:[1,2,NaN], B:[NaN,2,3] })
    Let this be your dataframe….
    To remove null values from a column you can use dropna function
    df.dropna(axis =0) # This will remove all the rows which have null values
    df.dropna(axis =1) # This will remove all the columns which have null values
