How does it feel to “Think you master Python” without really knowing the basics of the language?
This article was like a “Reader’s Digest” version of the first two chapters of any serious introduction to the Python language.
Everything mentioned is considered minimum required knowledge to even be considered as someone who has a “passing familiarity” with Python, and a long-winded way from being a “Master” IMO.
And, if you’re going to use graphs for conveying something, a graph would generally be a much better fit, if the result of a linear progression is not already crystal clear from using one simple sentence of easy to understand English, which is already present.
If this is the level of “mastery” todays developers are aiming for, well, good luck! It could probably land you a job at Google. As a lawnmower. Unless it requires Python skills to operate that is.
