How to use 2to3 properly for python?

Question

I have some code in python 2.7 and I want to convert it all into python 3.3 code. I know 2to3 can be used but I am not sure exactly how to use it.

Answer 1

To convert the code from python2 to python3 first install the 2to3 package by using

pip install 2to3

Then run this command in directory where is your python code

2to3 -w -n .

• -w flag to enable writeback, which applies the changes to the file
• -n to disable backups
