Microsoft adds Python support to its Teams development kit
Microsoft has released general availability for Python support in the Teams software development kit. Developers install the package through a standard pip command and gain access to the same core features as the TypeScript and .NET versions. The update includes decorator-based routing for handling activities, OAuth authentication, and type-safe connections to Microsoft Graph. It covers chats, channels, meetings, adaptive cards, proactive messages, and streaming responses. This marks the first time Python developers can build native Teams apps and agents without switching languages.
Until now, custom Teams app development depended on teams with skills in TypeScript or .NET, which kept the volume of bespoke extensions relatively low in organizations without dedicated development resources. Python support lowers that threshold, allowing a wider range of programmers to create agents and integrations that connect directly into Teams, which will increase the total number of apps that admins must track and secure.
Analysis
This change makes it simpler for anyone with Python knowledge to add new functionality to Teams, but it does nothing to address the existing sprawl of unmanaged apps and sites. Block all new custom app installations until you complete a full audit of current Teams and enforce a governance policy that covers app lifecycle from creation to deletion.
