[September 2025] Python Monthly Newsletter | Zero To Mastery

"Welcome to the 70th issue of Python Monthly! If it's your first time here, welcome, I like you already. If you want the full back story on this monthly newsletter, head here. The quick version: I curate and share the most important Python articles, news, resources, podcasts, and videos. Think the Pareto Principle (80/20 rule) meeting the Python world. I give you the 20% that will get you 80% of the results."

"Alright, let's not waste any valuable time and jump right into this month's updates. Here's what you missed in September 2025 as a Python Developer... Python, The Documentary 🎬 Yes, there is a new Python documentary that just came out, and I don't have to tell you that if you're a Pythonista, you have to watch it. It is very well done. Here is a good follow up read after you watch the documentary."

"Top Programming Languages 2025 📺 Usually these sort of articles are just clickbait trash, but this is one of the few places that gives good data and insight. You should check it out. As expected Python comes first followed by JavaScript (if you combine it with TypeScript, which you should). Does AI mean the end for the Top Programming Languages? Read the article and find out."

September 2025 highlights for Python developers include a new Python documentary that is highly recommended. Reliable rankings place Python first, with JavaScript (combined with TypeScript) following. The impact of AI on programming language popularity is questioned. Type checkers such as Ty, Pyrefly, and Zuban are evaluated for how effectively they add static typing to Python. Feature flags are described as a method to enable or disable code paths without redeploying software. Python 3.14 will introduce REPL syntax highlighting, and guidance is available to customize the REPL. A personal guide to choosing a programming language will be updated in December or January.
