Python: What's Coming in 2026

Overview & Executive Summary

If 2025 was “the year of type checking and language server protocols” for Python, will 2026 be the year of the type server protocol? “Transformative” developments like free threading were said to be coming to Python in 2026, along with performance-improving “lazy” imports for Python modules. We’ll (hopefully) also be seeing improved Python agent frameworks.

But 2026 could even see a change in change itself — in the ways that Python changes are proposed.

Last month, there was an illuminating seven-person conversation — including three of Python’s core developers, two of whom are also members of Python’s Steering Council. As 2025 came to a close, these prominent guests came together for a special year-in-review episode of the “Talk Python to Me” podcast, discussing what trends they’d seen in 2025 — but also what they see coming in the year ahead for Python and its developer community.

Architectural Breakdown & Technical Capabilities

From the beginning, the podcast showed that Python is still a broad-based global community. From Vancouver came Brett Cannon, a Python core developer since 2003, and a Microsoft principal software engineer for over 10 years. And what Cannon saw in 2025 was advances in people running Python code using tools.

Where before you’d install the Python interpreter — and then also any needed dependencies — to then launch everything in a virtual environment, “Now we’ve got tools that will compress all that into a run command!” A growing set of tools like Hatch, BDM and uv “build on each other and … just slowly build up this repertoire of tool approaches.”

This caught the attention of Python’s core developers. “These tools treat Python as an implementation detail, almost,” Cannon said. The Python interpreter just fades into the background as “a thing that they pull in to make your code run.”

Also on the call was Barry Warsaw, who has been a Python core developer for more than 30 years. He told Cannon, “I think you’re really onto something.” Warsaw is also on the 2026 Python Steering Council (while currently working on Python at Nvidia), and sees this as an even larger trend — “a renewed focus on the user experience.”

Implementation Details & Key Highlights

Just installing the binary with the Python interpreter can be complicated for new users, but 2024 saw Python adding a format for metadata to embed in Python scripts to help IDEs, launchers and other external tools. So in the world of 2025, it’s now that much easier to write code that will be run by Python. “You can put uv in the shebang line of your script — and now you don’t have to think about anything. And Hatch can work the same way for developers.”

This drew some enthusiastic agreement from Associate CS Professor Gregory Kapfhammer. Dialing in from Pittsburgh (where he’s already using uv in his classes at Allegheny College), Kapfhammer said he’s amazed how much uv had simplified lessons for his students. “I don’t have to teach them about Docker containers, and I don’t have to tell them how to install Python with some package manager.”

And from Berlin came more agreement from Jodie Burchell, a 10-year data scientist (now a developer advocate at JetBrains, working on PyCharm). Burchell said they’re even discussing whether to use uv at the data science mentoring community Humble Data (where she’s one of the organizers). “It does abstract away all these details. The debate I have is, is it too magic?” And as a developer advocate at JetBrains, “It’s also a debate we have in PyCharm. How much do you magic away the fundamentals versus making people think a little bit?”

This led to a discussion about possible future developments in Python. Core developer Cannon said that for the troubleshooters — and even just for the curious — “I want the magic to decompose. You should be able to explain the ‘magic’ path via more decomposed steps using the tool all the way down to what the tools actually do behind the scenes.” And it’s not just a hypothetical for him. “I’ve been thinking about this a lot,” Cannon said, because “I’m thinking of trying to get the Python launcher to do a bit more.”

After all, uv is still made by a company (named Astral), and “There’s always the risk they might disappear.” And a lot of work has now been put in place to create standards for this kind of packaging, including that metadata addition.
