Take the 2-minute tour ×  I was encouraged to step out of my
comfort zone and use python with little to no experience and now
I'm stuck. I'm trying to compare two CSV files (fileA.csv and
fileB.csv), and append any missing user rows to fileA.csv from
fileB.csv. The only fields I can compare with are user's first
and last names (in this case, it's row[0] and row[2] from each
file).  From my understanding, you cannot append information to
a file that you currently have open so I'm open to suggestions
without having to create a third file (if possible). Below has
me on the right track, but there's a lot of data so I'll need a
loop. Please help.  import csv reader1 =
csv.reader(open('fileA', 'rb'), delimiter=',', quotechar='|')
row1 = reader1.next() reader2 = csv.reader(open('fileB', 'rb'),
delimiter=',', quotechar='|') row2 = reader2.next()  ##For
Loop...          if (row1[0] == row2[0]) and (row1[2] ==
row2[2]):                 ## Compare next                  ##
Append entire row to fileA.csv  Example FileA.cs
