python - How to write UTF-8 in a CSV file

Question

I am trying to create a text file in csv format out of a PyQt4 QTableWidget. I want to write the text with a UTF-8 encoding because it contains special characters. I use following code:

import codecs
...
myfile = codecs.open(filename, 'w','utf-8')
...
f = result.table.item(i,c).text()
myfile.write(f+";")

It works until the cell contains a special character. I tried also with

myfile = open(filename, 'w')
...
f = unicode(result.table.item(i,c).text(), "utf-8")

But it also stops when a special character appears. I have no idea what I am doing wrong.

Answer 1

It's very simple for Python 3.x (docs).

import csv

with open('output_file_name', 'w', newline='', encoding='utf-8') as csv_file:
    writer = csv.writer(csv_file, delimiter=';')
    writer.writerow('my_utf8_string')

For Python 2.x, look here.
