Assignment 4: Baseball Fun With Classes Solution
Part 2
1. Your first task is to create a function with one parameter (a file name) that reads each line of data and creates a PlayersYear object from that line, then places it in a list. After all lines are read, this list of PlayersYear objects is returned to the main function.
2. Next, create a function with one parameter (the list of PlayersYear objects) to display all the players in a table proceeded by heading1.
3. Next, create a function with one parameter (the list of PlayersYear objects) to display the averages of each player in a table proceeded by heading2.
4. Next, create a function to get the key that permits sorting on the number of homeruns a player hits. This function has one parameter, (a Player object). This function returns the number of home runs hit by this PlayersYear object.
5. Next, create a function with one parameter (the list of PlayersYear objects) that sorts this list with respect to home runs.
6. Next, create a function to get the key that permits sorting on the number of at bats. This function has one parameter, (a Player object). This function returns the number of at bats of this PlayersYear object.
7. Next, create a function with one parameter (the list of PlayersYear objects) that sorts this list with respect to at bats.
8. Finally, the main() function (is where the functions are called) is described by the comments below:
◦ Ask user to enter file's name
◦ Read the data from the file, return a list of PlayersYear objects
◦ Display all stats of the players (heading1)
◦ Display all averages (heading2)
◦ Display all stats of the players sorted by homer
(heading1)
• Display all stats of the players sorted by at bats (heading1)
• Display all averages sorted from highest to lowest slugging percentage (heading2)
Deliverables:
Zip together, the files PlayersYear.py, assign4.py, baseball.txt, and
dimaggio.txt. Don’t forget to document each function!
Here are some outputs:
