Python Excel Program

my program shown below is one that reads data from a CSV file and imports it to PSSE. PSSE is a power flow simulation program. The program I have works.

My next goal is to read new data from new columns I put into my excel file COLUMNS[G to L]. This data I am trying to implement into this function psspy.two_winding_chng(from_busnum, to_busnum,VMAX,VMIN,'character value') Columns G through K are in order like the function value. The last parameter has to be implemented as a string value. So another thing is reading a variable on excel and transferring it as a string.

Finally my goal is to read data in Column G to L based off the program I have now where it takes the "year" and "location" and print out Columns B through E. Is there a way to do this? Also in Column L, that column represnts the data for the first, second, third year,etc.

Is there way to link column L and Column A. I can not use the xlrd, pandas modules or any other one, this the only module installed on the school computer. Excel sheet is posted. Columns A through L are described as: "year","busnum","busname","change","tla","location","from","to","max","min", 'character value', "year_linkup". My CSV sheet is posted here.[Excel Sheet][1]

PSSE_LOCATION = r "C:\Program Files (x86)\PTI\PSSE33\PSSBIN"

# assume CSV has columns as described in the doc string
