python - number of rows in two files different--> make equal by deleting from end -

 open(filename,"r") f:        reader = csv.reader(f,delimiter = ",")        data = list(reader)        rownum = len(data)  open(filename2,"r") f:        reader2 = csv.reader2(f,delimiter = ",")        data2 = list(reader2)        rownum2 = len(data)   if rownum > rownum2:        delete(rownum until rownum = rownum2 @ end) 

it's pretty simple.

data = data[:max(rownum, rownum2)] data2 = data2[:max(rownum, rownum2)]
