The command "pycodestyle ${file-py}" is a command-line command used to run the Python code style checker tool called "pycodestyle" on a Python file.

Here is the breakdown of the command:

• "pycodestyle": This is the name of the code style checker tool. It is used to enforce the Python style guide called PEP 8, which provides a set of guidelines and conventions for writing Python code.

• "${file-py}": This is a placeholder or variable that represents the name of the Python file on which you want to run the code style checker. The "${file-py}" indicates that you should substitute this placeholder with the actual name of the file you want to check. The ".py" extension suggests that it is a Python source code file.

By running this command, the pycodestyle tool will analyze the specified Python file and report any violations or inconsistencies with the PEP 8 guidelines. It will provide warnings or errors for style issues such as indentation, line length, variable naming, etc., helping developers maintain a consistent and readable code style.
