Answer 1

you could use pd.isnull() and sum:

df = pd.DataFrame([[1,1,1], [2,2,np.nan], [3,np.nan, np.nan]])
pd.isnull(df).values.sum()

which gives: 3

Answer 3

You can simply get all null values from the dataframe and count them:

df.isnull().sum()

Or you can use individual column as well:

df['col_name'].isnull().sum()
