How To Fix python-modernize: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu python-modernize is provided by modernize package.

modernize is:

This library is a very thin wrapper around lib2to3 to utilize it to make Python 2 code more modern with the intention of eventually porting it over to Python 3.

This package installs the python-modernize command line tool. It works like 2to3. It does not guarantee, but it attempts to spit out a codebase compatible with Python 2.6+ or Python 3. The code that it generates has a runtime dependency on six, unless the –no-six option is used. Version 1.9.0 or later of six is recommended. Some of the fixers output code that is not compatible with Python 2.5 or lower.

To fix this problem, we can install more using the command below.

sudo apt-get -y install modernize

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install modernize.

sudo apt -y install modernize

sudo aptitude install modernize
