2to3

$ 2to3 ${filename-py}

try on your machine

The command "2to3" is used to convert Python 2.x code to Python 3.x code. It is a utility provided with Python that helps in automating the conversion process.

In the command "2to3 ${filename-py}", ${filename-py} is a placeholder that represents the name of the Python file you want to convert. You need to replace ${filename-py} with the actual name of the file, for example, if your file is named "script.py", the command would be:

2to3 script.py

By running this command, the 2to3 utility will analyze the specified Python file and make the necessary changes to convert the code from Python 2.x syntax to Python 3.x syntax. This may involve modifying certain keywords, functions, or libraries that have changed between the two versions.

Note that the command may not modify the original file itself, but rather generate a new file with the converted code. It's important to review the changes and verify if the conversion was successful.
