In the early stages of the article you provide scripts with snippets of example code which carry out the script's stated functions. But it seems like you were over it long before you completed the article.
ReplyDeletePlease help readers to understand how a script that contains nothing but three comments:
# describe what this script should do
# code to carry out a function of the script
# code to carry out another function
I'm not sure how anyone could or would ever consider a script that contains no script, just comments (or worse yet, just a couple of lines of text that suggest tasks readers may wish to automate, without guidance, examples, tips or hints) to be among the 20 best python scripts. Very poor effort. I wonder how an article written by a LLM such as Chat GPT would have compared to what you've published here.
I agree, starts off well and then just "blank" code blocks.
DeleteInteresting question you asked there at the end, it would be very interetsing to comapre the two.
