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
