Writing On The Topmost Row Of A Csv File

I have this sample.csv file: a 1 apple b 2 banana c 3 cranberry d 4 durian e 5 eggplant And have the following code: samplefile = open(sample.csv,'rb') rows =

Solution 1:

If you want to add to the end of the file(append to it):

withopen("sample.csv", "a") as fp:
     fp.write("new text")

If you want to overwrite the file:

withopen("sample.csv", "w") as fp:
     fp.write("new text")

If you want to remove a line from file:

import fileinput
import sys

for line_number, line inenumerate(fileinput.input('myFile', inplace=1)):
  if line_number == 0:  #first linecontinueelse:
    sys.stdout.write(line)

If you want to add a new first line(before the existing one):

withopen("sample.csv", "r+") as fp:
     existing=fp.read()
     fp.seek(0) #point to first line
     fp.write("new text"+existing) # add a line above the previously exiting first line
