Vedansh is a Python programmer working in a school. For the Annual Sports Event, he has created a csv file named Result.csv, to store the results of students in different sports events. The structure of Result.csv is :
[St_Id, St_Name, Game_Name, Result]
Where
St_Id is Student ID (integer)
ST_name is Student Name (string)
Game_Name is name of game in which student is participating(string)
Result is result of the game whose value can be either 'Won', 'Lost' or 'Tie'.For efficiently maintaining data of the event, Vedansh wants to write the following user defined functions:
Accept() – to accept a record from the user and add it to the file Result.csv. The column headings should also be added on top of the csv file.
wonCount() – to count the number of students who have won any event.
As a Python expert, help him complete the task.
(i) Differentiate between r+ and w+ file modes in Python.
