Convert python 2 code to 3 in PyCharm

I found a way in Pycharm IDE to convert file from v2 to v3 using 2to3 tool.

I applied in pycharm comunity edition v 2016.2.3 in windows environment.

• click terminal in status bar Now, you are in shell command, in the root of your project.
• type the command (to convert myfile.py):

2to3 myfile.py -w

The tool modifies the code of the file, and your IDE is reflected with the changes.

To modify all your files in the folder, type the command

2to3 . -w

The option -w to actually write the changes. For more details write:

2to3 -h

Goto the folder where your python2script.py is existing in command line,

then execute the command:

python C:/python/Tools/scripts/2to3.py -w python2script.py

you can see that your python2scipt.py is updated.

In order to convert your python script from version-2 to version-3, you can simply use 2to3 utility.

On linux terminal -

$ 2to3 my_file.py              # shows output only on terminal

or

$ 2to3 -w my_file.py           # overwrites the file with python-3 code

where my_file.py is the file which you want to convert.

Two methods to convert python 2.X.X to python 3.X.X

1. Using Web-application

I develop a web application to convert python 2.x.x code to python 3.x.x. Here is the Automatic Python 2 to 3 converter.

Note: This web app is FREE and using this 2to3 python library.

2. Using 2to3 library, Read the doc here.

Install 2to3 library

pip install 2to3 

Convert myfile.py

2to3 myfile.py 

This commends create a new file that contains your Python 3 code.

If you want to overwrite the myfile.py use -w argument like 2to3 myfile.py -w. Read the docs for more arguments.
