Pandas Optional Challenge #3 - Verified Email List

I have been stuck on this challenge for a while and can't make any more progress. Here is the challenge:

TODO: Narrow list to those that have email verified. '''python email_list = users[users.email_verified == True] ''' TODO: The only columns should be first, last and email

email_list = email_list.loc[ : , ['first_name', 'last_name', 'email_verified']]

TODO: Remove any rows missing last names

email_list.dropna(inplace = True)

TODO: Ensure that the first names are the proper case

email_list.loc[ email_list.first_name.str.islower() , 'first_name'] = email_list.first_name.str.title()

TODO: Return the new sorted DataFrame..last name then first name ascending

email_list.sort_values(by=['last_name','first_name'], ascending = [True,True])

email_list

Any help appreciated

I realized I need inplace = True when sorting the values as I was only sorting a copy before that
