The command "2to3 --list-fixes" is used to display a list of fixes available in the 2to3 tool.

2to3 is a tool provided in Python to aid in converting code written in Python 2.x to Python 3.x. The tool automatically detects and applies various fixes to update the code syntax.

When you run the "2to3 --list-fixes" command, it will display a list of fixes that can be applied by the 2to3 tool. Each fix represents a specific change that can be made to the source code during the conversion process. The list will typically include fixes for various syntax updates, such as replacing print statements with print functions, updating the built-in functions, handling unicode, standard library changes, and so on.

This command is useful because it helps developers understand the changes that will be made to their code before actually running the conversion process with the 2to3 tool. It allows them to review the list and see if any specific fixes need to be excluded or included during the conversion process based on their requirements.

By examining the list of fixes, developers can make informed decisions about how they want the conversion process to handle specific changes in their code, ensuring a smoother transition from Python 2 to Python 3.
