2to3: Convert all Python 2 language features except the specified ones to Python 3.

2to3

$ 2to3 --write ${filename-py} --nofix=${has_key} --nofix=${isinstance}

try on your machine

The command you provided is using the "2to3" tool, which is a tool used to convert Python 2 code to Python 3. Let's break down the different parts of the command:

"2to3": This is the name of the command or tool that is being executed. It is used to run the Python 2 to Python 3 conversion.
"--write ${filename-py}": This part of the command specifies the file that you want to convert. The "${filename-py}" is a placeholder for an actual Python file name. You need to replace it with the actual name of the file. For example, if your file is named "example.py", you would replace "${filename-py}" with "example.py". The "--write" option tells the tool to write the changes directly to the file.
"--nofix=${has_key}": This part of the command is specifying an option to disable a specific fix. The "${has_key}" is another placeholder for a fix name that you need to replace with the actual fix you want to disable. For example, if you want to disable the "has_key" fix, you would replace "${has_key}" with "has_key". This option is used when you want to prevent a specific fix from being applied during the code conversion.
"--nofix=${isinstance}": Similar to the previous option, this part of the command is specifying another fix to disable. Again, "${isinstance}" is a placeholder for the fix name that you need to replace with the actual fix you want to disable. For example, if you want to disable the "isinstance" fix, you would replace "${isinstance}" with "isinstance".

In summary, this command is using the 2to3 tool to convert a Python 2 file to Python 3, and it is disabling two specific fixes named "has_key" and "isinstance" during the conversion.
