This week a Python basics tutorial hit the trending page on Juejin, titled "Python Zero-Basis Core Advancement: The Most Complete Guide to Four Containers + Functions on the Web." Set against the 2026 backdrop of AI writing code automatically, this is worth a closer look.
What this is
The tutorial covers the four data containers — lists, tuples, dictionaries, and sets — plus function fundamentals, variable scoping, and five parameter-passing methods. The author emphasizes "code that runs straight out of the box, readable by absolute beginners," positioning it as entry-level, interview prep, and exam review. A typical long-form technical post, its target readers are career switchers chasing the AI wave, or candidates cramming for interviews.
Industry view
The tutorial's continued popularity signals strong demand: AI and data roles are still hiring in volume, Python's position as the de facto standard stack holds firm, and corporate training budgets keep tilting this way.
But there's a flip side worth flagging. AI coding assistants (Cursor, Copilot, Tongyi Lingma, etc.) have already automated most of the "writing syntax" work. We notice a contradiction: beginner tutorials are multiplying, yet what companies actually need are "people who can use AI to ship usable products." In other words, memorizing lists and dictionaries gets you a ticket; being able to call a model API in Python and handle real-world data is where real entry begins. Most long-form readers stall at the "I finished reading but still can't use it" stage — and that gap itself is the market opportunity.
Impact on regular people
For enterprise IT: Treating "knows Python" as a hard hiring bar is already outdated. What matters is whether candidates can collaborate with AI tools to ship real projects.
For individual careers: Non-programmers learning Python is still worth it, but the goal should be "solving concrete business problems" (automated reports, data cleaning, batch file edits) — not stopping after grinding through syntax.
For the consumer market: Python and AI intro courses are oversupplied — everything from 9.9 RMB to over 10,000 RMB exists. When choosing, look for project-based practice rather than course-hour counts.
