I keep getting an error for this and not sure what I'm doing wrong. The rest of my code up until here works fine.

I've since fixed part of the error, but I keep getting this syntax error and I'm not sure why..

1. firstly do the filtering trick as below:
   dataframe[dataframe['this_column'] == 'that_value']
2. note that .loc method filters for the column labels in the dataframe. if you have a series it already contains one column
3. put closing square bracket in mean_price variable, as below:
   mean_price = brand_only.loc[['price']].mean()
4. note that nested square brackets are only used in case of multiple columns, when you only need one column, it is safe to put the column label with single pair of square brackets, i.e. .loc['price']

@MariamAmmar: you have an extra square bracket [ in mean_price = brand_only.loc['price'].mean().
