python - How to use 2to3 tool in windows?

Question

I tried to modify the sintax using 2to3 tool by running command

python C:Python32Toolsscripts2to3.py neo4j.py

and got the output

When opening neo4j.py however I noticed there hasn't been anything changed. Below is the block of code where changes (accoridng to output) should be made:

try:
    import json
except ImportError:
    import simplejson as json
try:
    from urllib.parse import quote
except ImportError:
    from urllib import quote
try:
    from . import rest, batch, cypher
except ImportError:
    import rest, batch, cypher
except ValueError:
    import rest, batch, cypher

import logging
logger = logging.getLogger(__name__)

Does anyone know how to use 2to3 tool properly in order to port/change the code to v3.2?

Answer 1

You have to use the -w flag to actually write the changes:

python C:Python32Toolsscripts2to3.py -w neo4j.py

See the 2to3.py documentation.
