Write a Python program that creates a file named grades$2.$csv$.$ The new file should contain all of the information from grades.csv In addition, there should be a fourth column entitled Average. For each student, the value in the new column should be the average of the two grades.

excel output:

Cooper, $85,95$

Eli, $85,80$

Leah, $100,96$

Gabe, $71,100$

Amber, $75,89$

python code:

infile $=$ open$("$grades$.$csv$","$r$")$

outfile $=$ open$("$grades$2.$csv$","$w$")$

aline $=$ infile.readline$()$

outfile.write$("\backslash$t$"+$"Average

$")$

while aline:

items $=$ aline.split$()$

dataline $=$ items$[0]+"\backslash$t$"+$ items$[1]+"\backslash$t$"+$items$[2]$ #$+"\backslash$t$"+$ items$[3]$

outfile.write$($dataline $+"$

$")$

aline $=$ infile.readline$()$

print$($aline$)$

infile.close$()$

outfile.close$()$
