[Tutor] reading and writing with csv then appending some data to a specific line

[pierre cutellic]

Hi,
I wrote this script to select some data from a csv file.
Actually it writes it into a file but i would like to append it into an
existing one to a specific line without removing existing code.
 does the open('filename.csv','a+') can do that?

here is the existing code:


*import csv
import sys

def rawdata():

    rawdata = []
    catched = []
    f = open('datalisting_000.csv','r')#the file to read to(!same path)

    try:

        reader = csv.reader(f)

        for row in reader:

            rawdata.append(row)

    finally:

        f.close()

    del rawdata[0]

    for elem in rawdata:

        ag = elem[0]
        ag.split(";")
        catched.append(ag)

    return catched

def sendingraw():

    ff = open('data.py','w')#the file to write to(!same path)
    ff.write(str(rawdata()))
    ff.close()

sendingraw()*

Cheers
