  • simplest version
name = 'hello world from example'
print type(name)  # <type 'str'>
print name        # hello world from example
  • add some non-english chars, a SyntaxError will be raised
name = 'helló wörld from example'  # name = u'helló wörld from example' does not help
print type(name)
print name

# SyntaxError: Non-ASCII character...
# means you need add head-comment # encoding: utf-8
  • so you need add head-comment # encoding: utf-8 or # -*- coding: utf-8 -*-(which is more standard) to fix it
# encoding: utf-8

name = 'helló wörld from example'
print type(name)  # <type 'str'>
print name        # hello world from example
  • but # encoding: utf-8 won't change the fact that unicode and str are different in Python 2.7
# encoding: utf-8

name = u'helló wörld from example'
print type(name)  # <type 'unicode'>
print name        # hello world from example
  • so you need the __future__ package
# encoding: utf-8
from __future__ import unicode_literals

name = 'helló wörld from example'  # name = u'helló wörld from example' is just in vain, they have the same effect
print type(name)  # <type 'unicode'>
print name        # hello world from example
  • if you want to go back to str type, you need explicitly specify b before ''
# encoding: utf-8
from __future__ import unicode_literals

name = b'helló wörld from example'
print type(name)  # <type 'str'>
print name        # hello world from example
