An interesting tweet. The roadmap has three sections. I'm not sure this is actually complete, or even grouped correctly. It is a very good list of topics.

"Here's a complete roadmap of topics to master Python."

The thread, however, seems no longer …

The SOLID design principles beat the design boundary issue to death. Here are the principles in my preferred order. (See https://www.linkedin.com/learning/learning-s-o-l-i-d-programming-principles)

1. Interface Segregation -- minimize the boundaries. Do this first.
2. Liskov Substitution -- keep the boundaries consistent. Do this for hierarchies.
3. Open/Closed -- keep the boundaries stable …

See https://slott56.github.io/replacing-a-spreadsheet/. This document is really exciting (to me).

This is still shaky -- I'm still learning -- but it's a very cool combination of Python components sympy and Jupyter Lab. As a bonus, Jupyter{Book} appeals to me as a writer. There's an aspect of literate programing …

Let's talk about profound confusion.

I got an email with a subject of this, "Python's Protocol Reduces Reliance on Duck Typing". The resulting conversation led to this nugget: "... my current project could use protocols in Python, and thus I didn't need to rely on duck typing and instead could use …

I heard about these less than a week ago.

This is very interesting. Very interesting.

See A 5-Point Framework For Python Performance Management.

It seems straight-forward to me. Have goals. Measure your ability to meet them.

I don't see too many teams doing this, though.

I could be wrong, but, I think performance is left to arguments and complaints, not solid engineering.

I get asked about good books for beginners. Here's an example:

"What Python books do you recommend for novices so they can learn from beginner to advanced?"

For me, this is nearly impossible to answer.

"Beginner" is often undefined. I have to turn this around and ask what you already …

It's hard to write shameless promotional material.

I already wrote the books, isn't that bold enough?

It isn't, though.

Packt’s Head of Product, Oli Huggins, said: “We believe in helping to serve and support the global developer community. By selling our eBooks and Videos for $5, we hope to …

See https://www.geeksforgeeks.org/find-the-smallest-positive-number-missing-from-an-unsorted-array/ This seems to be a popular coding interview problem.

The Python code shown on the site seems almost maliciously misleading.

The full problem is this:

You are given an unsorted array with both positive and negative elements. You have to find the smallest positive …
