Now it's your turn to remove rows with wrong data!

Завдання

Get indexes of rows having 'inconsistent' data. Follow the next steps:

Apply the .loc[] property to the df dataframe.
Set condition on rows: row sums of 2-14 columns ([2:15]) must be not equal to values in the 'hhsize' column.
Use the .index attribute.

Drop rows using indexes saved within ind variable. Set the inplace parameter to rewrite the changes.
