Hello all, I have a list: suffix = ["aĉ", "ad", "aĵ", "an", "ar"] and I'm trying to check a word to see if any of the suffixes exist in the list for example: if word in suffix: print "A suffix exist in your word" when I run this it give me an error: SyntaxError: Non-ASCII character '\xc5' in file vortaro.py on line 33, but no encoding declared; is there a way to parse Non-ASCII characters in python?

print from a python script.
I'm trying to print a simple string to a network printer. This is what I
have so far:
import os
printer_path = "192.168.200.139"
p = os.popen(printer_path, 'w')
p.write("this is a printer test")
p.close()
I'm trying to call the printer from its IP address. When I run the script I
get:
sh: 192.168.200.139: not found
thanks for you help in advance.

It throws an error with that file name, When I change it to something like
