• The 2025 Typed Python Survey, conducted by contributors from JetBrains, Meta, and the broader Python typing community, offers a comprehensive look at the current state of Python’s type system and developer tooling. • With 1,241 responses (a 15% increase from last year), the survey captures the evolving sentiment, challenges, and opportunities around Python typing in the open-source ecosystem. • In this blog we’ll cover a summary of the key findings and trends from this year’s results. • The survey was initially distributed on official social media accounts by the survey creators, and subsequently shared organically across further platforms including Reddit, email newsletters, Mastodon, LinkedIn, Discord, and Twitter. • When respondents were asked which platform they heard about the survey from, Reddit emerged as the most effective channel, but significant engagement also came from email newsletters and Mastodon, reflecting the diverse spaces where Python developers connect and share knowledge. • The respondent pool was predominantly composed of developers experienced with Python and typing.
Article Summaries:
- The 2025 Typed Python Survey, run by JetBrains, Meta and the broader typing community, gathered 1,241 responses-a 15 % rise over last year-to gauge Python’s type system. 86 % of respondents said they “always” or “often” use type hints, a figure unchanged from 2024. Adoption is strongest among developers with 5-10 years of experience (93 %), slightly lower for newcomers (83 %) and senior veterans (80 %). Reddit proved the most effective outreach channel, with email newsletters and Mastodon also driving participation. Respondents cited code quality and flexibility as the top motivations for adopting typing.
