Unicode error when writing russian symbols to csv

Question

I want to write cyrillic symbols to csv file but I get unicode encode error. English symbols works perfect. I'm using Python 3.6.2.

UnicodeEncodeError: 'ascii' codec can't encode characters in position 1-6: ordinal not in range(128)

import csv


with open("test.csv", 'w') as csvfile:
    csvfile = csv.writer(csvfile, delimiter=',', quotechar='|', quoting=csv.QUOTE_MINIMAL)
    hello = 'привет, мир!'
    csvfile.writerow([hello])

Answer 1

Declare the encoding of the file when you open it. newline='' is also required per the csv documentation.

import csv

with open('test.csv','w',encoding='utf8',newline='') as csvfile:
    csvfile = csv.writer(csvfile, delimiter=',', quotechar='|', quoting=csv.QUOTE_MINIMAL)
    hello = 'привет, мир!'
    csvfile.writerow([hello])
