I use:
f = open("my_file.csv", "a")
writer = csv.writer(f)
writer.writerow(['one', 'two'])
But instead of appending a new row after the last row, it appends 2 new rows: an empty one and then the required one "one| two". What is the reason for that?
I find it easier to use with open()
when writing to csv files. The documentation can be found here . I can reproduce the problem you had on my machine, but the following code does not produce an empty line after each new line is appended.
import csv
with open('my_file.csv', 'a', newline='') as csvfile:
writer = csv.writer(csvfile, delimiter=',')
writer.writerow(['one', 'two'])
