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.
