For a python class I am taking.. In this challenge, you'll be working with a DataFrame that contains data about artworks, and it contains many missing values.
Your task is to create a variable called na_sum that contains the total number of missing values in the DataFrame. When that's completed, print out your answer! Hint: The code given below will give you the number of missing (NaN) values for the *Name* column in the DataFrame. How would you edit the code to get the missing values for every column in the DataFrame? Extra hint: You'll be returning a single number which is the final sum() of everything. df['Name'].isnull().sum() -- Thanks! *Sarah Wallace* sarah.wallac...@gmail.com -- Thanks! *Sarah Wallace* sarah.wallac...@gmail.com 214.300.1064 -- https://mail.python.org/mailman/listinfo/python-list
