Problem description & analysis
We have a txt file data1.txt, as shown below:
ID,Name,LastName,Department
12345,John,Samon,Computer Science
14524,David,Souza,Electric and Electronic
And another txt file data2.txt, as shown below:
ID,Q1,Q2,Q3,Midterm,Final
12345,100,90,75,89,100

The two files associate through their IDs in a one-to-one relationship. We are trying to generate a new text file as follows:
ID,Name,avgQ_Average,Midterm,Final,Department
12345,John,88.33,89,100,Computer Science
14524,David,71.67,15,90,Electric and Electronic
