This hybrid (both remote and in-person) conference is a joint effort and a collaboration between PyConDE and PyData Berlin, hence there will be dedicated tracks for each area.

Please go to our Pretalx website to submit your proposals. You will need to set up an account there (it can be deleted by you anytime), and you can edit your proposals until the Call for Proposals closes.

Please feel free to forward this call to anyone you think might be interested in submitting a proposal.

PyConDE brings together developers, programmers, DevOps, scientists, and others from the Python community to discuss application techniques, updates to the language, further Open Source development, and talk community. Our talks often include new features of the Python language, new libraries, security, testing, web, and programming & software engineering in general.

PyData brings together analysts, scientists, developers, engineers, enthusiasts and others from the data science community to discuss applications of new tools and techniques within data science. Our talks often include data management, analytics, visualisation as well as new machine learning, statistical, and deep learning approaches.

Conference Tracks & Topics of Interest

The conference will feature three main tracks. In total there will be about 80-100 talks.

  1. PyData topics,
  2. PyCon topics,
  3. General topics that do not fall into former categories.

Tutorials can be given in each of the tracks above. In order to simplify the review process and the creation of the program, you must select a track with a topic for your talk from the list below:

  • DevOps & MLOps
  • Django
  • Libraries
  • Programming & Software Engineering
  • Python Language
  • Security
  • Testing
  • Web
  • Computer Vision
  • Data Handling
  • Deep Learning
  • Jupyter
  • Machine Learning & Stats
  • Natural Language Processing
  • PyData & Scientific Libraries Stack
  • Visualisation
  • Community, Diversity, Career, Life and everything else
  • Ethics & Privacy
  • Infrastructure - Hardware & Cloud
  • Python & PyData Friends
  • Production
  • Others

We also welcome presentations focusing on a variety of topics all around Python and Data (incl. languages as R, Julia, Scala, and Rust). To see the presentation of previous events, please look at our past conference videos on YouTube at PyData, PyConDE.

Presentation Format

Presentation content can be at a novice, intermediate or advanced level. Talks will have two possible lengths, either 30 or 45 minutes, and hands-on tutorials will last 90 minutes.

Accepted speakers will receive a free ticket to attend the conference. Travel expenses will not be paid; but we do have a diversity travel program and encourage speakers with diverse backgrounds to apply for travel funding.

Submission Process

Please go to our Pretalx website to submit your proposals through a webform. After you submit a talk proposal, the conference committee will review the proposals and communicate any needed feedback or improvements. We aim to include many first-time speakers, and therefore will attempt to communicate and iteratively help you improve the abstracts.

Your Submission

In our experience, attendees pay close attention to proposal abstracts when deciding which talks to attend during the conference. The submitted abstract will be published as is in the conference program (you can edit the submission later).

We encourage you to include details about the theory, concepts and/or practice you will discuss. Specifically, if the system you've built uses open source tools, please mention the libraries in the proposal and make it clear whether you will be presenting a case-study of their use or if you will discuss details of their design.

In general, conference attendees, as well as the review committee, should be able to answer these questions based on your submission:

  • What problem is your talk addressing (are you talking about a well-known problem, or have you found something new during a project)?
  • Why is the problem relevant to the audience?
  • What is(are) your solution(s) to the problem, or are you simply pointing out the fact there is an issue we should be aware of (this can also be extremely useful)?
  • What are the main takeaways from your talk? For a tutorial submission, this is extremely important, please specify what people will have learned at the end of the tutorial session.

Important Dates

Talk Proposal Deadline: 9 January 2023 23:59:59 CET

Acceptance Notification: 13 February 2023

Conference Dates: 17-19 April 2023

Health Restrictions

In April the conference might still face health restrictions. International travel might be restricted from/to parts of the world. Hence we have included an additional remote option for speakers and attendees.


We are excited to announce that we will offer all-day childcare at the venue. During the conference hours, there will be a dedicated area with childcare professionals who will look after your children. In order to use our childcare services, we ask that you register a separate, free ticket below and let us know everything that is important to keep your child happy during the conference. Please note that places are limited and available on a first-come-first-serve basis. You can register your childcare free ticket here once the ticket sales are opened. We look forward to welcoming you and your children to the conference!

Diversity & First-Time Speakers

We especially encourage first-time speakers and submissions by underrepresented members of the community. If you are interested in presenting a talk or tutorial, we welcome your submission(s).

We are collaborating with the PyLadies Berlin, this group organised a mentorship event in the past. We hope to offer a mentorship event again this year and will keep you updated on that.

Diversity Travel Sponsorship

As a volunteer-run and non-profit supported conference, we cannot offer travel sponsorship for speakers. However, as part of our diversity program, we do have a limited number of travel scholarships for attendees and speakers. You can learn more about the scholarship on our Diversity Program page, where you can also apply for a scholarship. If you or your company is interested in helping increase diversity at PyConDE & PyData Berlin, we encourage you to reach out to info@pycon.de, since we have several sponsorship opportunities available (https://de.pycon.org/sponsors/).


PyConDE and PyData are both volunteer-run conferences. They support open-source development by donating all proceeds to Python Verband e.V. and NumFOCUS, a non-profit organisation that supports the development of open-source tools, such as Numpy, IPython, Jupyter, and many others.

Open Source

As a reminder, PyConDE and PyData presentations are intended to share knowledge and experience. To this end, we encourage the code and/or data that your talk relies on to be open-source. Ideally, the audience would have access to the necessary tools to reproduce the results of the talk. Also, we welcome talks focused on your own practical application of tools and concepts either at work or in your free time, but discourage sales-oriented proposals whose sole aim is to sell a product.

We strive to maintain the Python community’s reputation for being welcoming, friendly, and supportive. To this end, we ask all attendees, organisers and sponsors to follow the Code of Conduct


The mission of the US 501(c)3 public charity is to promote sustainable high-level programming languages, open code development, and reproducible scientific research.

Python Software Verband

Is a public charity supporting and furthering the Python language in Germany, Austria, and Switzerland.

Meet and engage with Python developers and enthusiasts at the conference. This conference is an excellent opportunity to present your company, organisation, and products or services to a friendly and interested audience.
