Analyzing baseball stats with .apply()

The Tampa Bay Rays want you to analyze their data.

They'd like the following metrics:

The sum of each column in the data
The total amount of runs scored in a year ('RS' + 'RA' for each year)
The 'Playoffs' column in text format rather than using 1's and 0's

The below function can be used to convert the 'Playoffs' column to text:

def text_playoffs(num_playoffs): 
    if num_playoffs == 1:
        return 'Yes'
    else:
        return 'No'

Use .apply() to get these metrics. A DataFrame (rays_df) has been loaded and printed to the console. This DataFrame is indexed on the 'Year' column.

1
Apply sum() to each column of rays_df to collect the sum of each column. Be sure to specify the correct axis.
2
Apply sum() to each row of rays_df, only looking at the 'RS' and 'RA' columns, and specify the correct axis.
3
Use .apply() and a lambda function to apply text_playoffs() to each row's 'Playoffs' value of the rays_df DataFrame.
