[Practice]
Create a CSV file the same as the below one, and then save it as a CSV file. Name the file as "students2.csv." Make sure that the file extension is not "txt."

[CSV File] students2.csv
ID,Name,Score
1071,John Smith,80
1072,Linda Brown,55
1073,Bill Sutton,100
1074,Harry Cox,65
1075,Marty Stewart,75

Judge all students' scores in the "students2.csv." The grade is decided according to the below criteria. Let's code that all students' ID, name, score, and grades are written in the new CSV file as a "result.csv."

[Grade]
・Grade A: The score is greater than or equals to 90.
・Grade B: The score is less than 90, and it is greater than or equals to 75.
・Grade C: The score is less than 75, and it is greater than or equals to 60.
・Grade D: The score is less than 60.
・Grade F: We cannot judge the score.

[Specification]
・In the first line of the new CSV file, add the Grade column next to the Score.
・Don't forget to break a line.
・Convert a "String" data to an "int" type value, like this.
