[python] NameError: global name 'unicode' is not defined - in Python 3

I am trying to use a Python package called bidi. In a module in this package (algorithm.py) there are some lines that give me error, although it is part of the package.

Here are the lines:

# utf-8 ? we need unicode
if isinstance(unicode_or_str, unicode):
    text = unicode_or_str
    decoded = False
    text = unicode_or_str.decode(encoding)
    decoded = True

and here is the error message:

Traceback (most recent call last):
  File "<pyshell#25>", line 1, in <module>
    bidi_text = get_display(reshaped_text)
  File "C:\Python33\lib\site-packages\python_bidi-0.3.4-py3.3.egg\bidi\algorithm.py",   line 602, in get_display
    if isinstance(unicode_or_str, unicode):
NameError: global name 'unicode' is not defined

How should I re-write this part of the code so it works in Python3? Also if anyone have used bidi package with Python 3 please let me know if they have found similar problems or not. I appreciate your help.

The answer is

One can replace unicode with u''.__class__ to handle the missing unicode class in Python 3. For both Python 2 and 3, you can use the construct

isinstance(unicode_or_str, u''.__class__)


type(unicode_or_str) == type(u'')

Depending on your further processing, consider the different outcome:

Python 3

>>> isinstance('text', u''.__class__)
>>> isinstance(u'text', u''.__class__)

Python 2

>>> isinstance(u'text', u''.__class__)
>>> isinstance('text', u''.__class__)

Hope you are using Python 3 , Str are unicode by default, so please Replace Unicode function with String Str function.

if isinstance(unicode_or_str, str):    ##Replaces with str
    text = unicode_or_str
    decoded = False

You can use the six library to support both Python 2 and 3:

import six
if isinstance(value, six.string_types):

If you need to have the script keep working on python2 and 3 as I did, this might help someone

import sys
if sys.version_info[0] >= 3:
    unicode = str

and can then just do for example

foo = unicode.lower(foo)
