PyCon US is the largest annual Python programming conference held in the United States, serving as a premier gathering for the Python community. The conference attracts over 2,000 attendees from around the world and has established itself as a central hub for Python developers, educators, and enthusiasts to share knowledge, collaborate on projects, and advance the Python ecosystem 1).
PyCon US is organized and run by the Python Software Foundation and volunteer community members. The conference operates as a non-profit event dedicated to fostering collaboration and education within the Python programming community. It provides a structured yet inclusive environment where participants at all skill levels—from beginners to advanced practitioners—can engage with the broader Python ecosystem.
The conference format combines multiple presentation and interaction modalities to accommodate diverse learning preferences and networking opportunities. The event spans several days and typically occurs in late spring, with PyCon US 2026 scheduled for May 13-19 in Long Beach, California 2).
PyCon US features a comprehensive program structure designed to maximize participant engagement and knowledge sharing. Keynote presentations from prominent Python community members set the tone for the conference and address significant developments, trends, and visions for the Python language and ecosystem.
The main conference programming includes talks of varying lengths, typically 25-45 minutes, where speakers present on topics ranging from core language features to domain-specific applications. These talks cover subjects including web frameworks, data science, machine learning, DevOps, testing practices, and architectural patterns.
Lightning talks provide a fast-paced format where speakers deliver brief presentations—typically 5 minutes—on specific projects, tools, or ideas. This format encourages rapid knowledge transfer and enables emerging speakers to gain presentation experience with lower barriers to entry.
Sprints are hands-on collaborative sessions where attendees work together on open-source projects. Sprints typically occur at the end of the conference and provide direct mentorship from experienced maintainers, making them valuable for contributors seeking to deepen their involvement with significant Python projects.
Open spaces offer informal discussion forums where participants can self-organize discussions on specific topics not necessarily covered in the formal schedule. These sessions foster grassroots community dialogue and enable ad-hoc knowledge sharing.
PyCon US functions as a critical gathering point for the Python community, facilitating networking among developers, companies, educators, and open-source project maintainers. The conference strengthens the Python ecosystem by encouraging collaboration, showcasing innovations, and providing platforms for community members to showcase their work.
The event maintains a strong commitment to accessibility and inclusivity, with diverse scholarship programs and community support initiatives aimed at enabling participation from underrepresented groups in technology. Attendees represent various sectors including academia, software development companies, financial services, data science organizations, and non-profit institutions. Despite its growth to over 2,000 attendees, PyCon US is notable for maintaining a distinctly community-focused atmosphere, standing out among similar-sized technical conferences as having a less corporate feel 3).
With attendance exceeding 2,000 participants, PyCon US represents one of the largest Python-focused conferences globally. The conference requires substantial venue infrastructure to accommodate keynotes, multiple parallel sessions, exhibition spaces, and collaborative areas. The 2026 edition takes place in Long Beach, California, a location providing accessibility and infrastructure suitable for the conference's scale 4).
