Using Pandas

  Initially I converted the Excel file into five csv files for each sheet in excel file.
  Then, I wrote a code in Python using Pandas for extracting answer keys and marks for each question in the test 1 
  and inserting in a dataframe.
  
  Then I used the responses of each student from the third sheet, compared the marks with the answer key 
  and assigned the marks in case of correct attempt

   In a directory, Store all the data files in a folder named 'data': 1.csv, 2.csv etc
   
   Install the requirements:
   Mainly Pandas
   
   Run the file code.py
