In Python, we are using the following file to generate a scatterplot given the text file below.

Shown below is my python code, which works as it is to generate one scatterplot with sepal length as x-axis and petal width as y-axis.

However, my code must incorporate a command-line interface (using the argparse module) with the following:

In other words, I should be able to use any of the four continuous width/length columns as either my x or y value using the argparse function. I should also be able to specify the include of categorical value (the class column) specified by the argparse function.

Please tell me how I can implement a command-line interface in my code.
