How to make program work and write it to csv file?

Answer 1

I ran your code and it works without throwing any errors. Only thing is that your csv file contains byte encoded values. Values with ab' at the front. Is this what you were trying to accomplish? I am using python 3.5.2 .

In the event you do not want byte encoded data just remove the

a = [s.encode('utf-8') for s in a]

And it should work. Here is the output of your data into the csv when I ran it on my machine.

# encoding=utf8  
import sys  

reload(sys)  
sys.setdefaultencoding('utf8')
