I have a simple sample script written in python2. Since we are migrating to python3, I am trying to get familiar with the tools that ae present. The modernize tool, helps me to achieve a python3 code. I run it, I get the result expected.
However, modernize promises backward compatibility, I expect the newly generated code to run in python2 as well.
While running with python2 Interpreter, I face issues as shown below:
Eg: Sample.py
import Queue
from urllib2 import urlopen
def greet(name):
print 'Hello',
print name
print "What's your name?",
name = raw_input()
greet(name)
From the directory on the commandline
python-modernize -w Sample.py
New Sample.py:
from __future__ import absolute_import
from __future__ import print_function
import six.moves.queue
from six.moves.urllib.request import urlopen
from six.moves import input
def greet(name):
print('Hello', end=' ')
print(name)
print("What's your name?", end=' ')
name = input()
greet(name)
I run the new script from the command line. Produces correct results.
py Sample.py
However, since it is backward compatible, when I do the following I get errors:
C:\Python27\python.exe Sample.py
Traceback (most recent call last):
File "Sample.py", line 3, in <module>
import six.moves.queue
ImportError: No module named six.moves.queue
Should the new script be modified again? Is modernize not fully backward compatible? Please let me know

Did you install the six module ?
pip install six

The answer for this is on the same regard as pip installing libraries in different versions. I was installing the library in python3. So now I managed to get it done on python2. Refer here
