append new row to old csv file python

Question

hi, I am trying to add new row to my old csv file. Basically it get update each time when I run the python script. Right now I am storing the old csv rows values in list and then deleting the csv file and creating it again with the new list value.

Wanted to know is there any better ways of doing it.

Thanks

Answer 1

fd = open('my.csv','wa')
fd.write(myCsvRow)
fd.close()

Opening a file with the 'wa' parameter allows you to append to the end of the file instead of simply overwriting the existing content. Try that.

Answer 2

Are you opening the file with mode of 'a' instead of 'w'?

Answer 3

Still can solve the problem

Thanks
