Are tickets refundable?

Tickets are fully refundable until 27 March 2026 no questions asked.

What payments option do you offer?

We accept:

  • Bank transfer [actually our preferred method]
  • Credit card (via Stripe)
  • PayPal (for non SEPA countries)

PayPal charges high fees, which is why we offer PayPal only for non-SEPA countries. Within SEPA (the European Single Euro Payments Area), a simple bank transfer is recommended.

Can I sent you a purchase order for tickets?

Unfortunately, purchase orders are only accepted from sponsors. All other tickets must be purchased directly through the ticket shop.

If tickets need to be purchased by another department, please coordinate internally to complete the transaction through the ticket shop. Purchase orders sent by email or fax will not be processed. Procurement-based purchasing is available exclusively to sponsors.

Can tickets be paid by invoice and bank transfer?

Yes. Tickets can be purchased by invoice and paid via bank transfer through the ticket shop.

Please make sure to download the invoice immediately after purchase and ensure it is processed correctly by your bookkeeping or procurement department. All funds must be received within the stated payment term; unpaid tickets will be canceled automatically. Conference tickets will be issued once payment has been processed on our side.

Please note that while we understand there may be delays in internal procurement processes, the conference cannot accept any payment delays or provide additional paperwork, supplier onboarding, or custom processing for purchase systems. If this is not feasible, we recommend completing the purchase via credit card instead.

What is included in terms of food and drinks during the conference?

The conference ticket includes a light lunch buffet, coffee breaks, and light refreshments throughout the day.

Which food options are there?

While every effort is made to provide a diverse selection, some options may be limited due to local conditions. The planned options include:

  • gluten-free
  • lactose-free
  • meat
  • vegan
  • vegetarian

All food will be labeled for allergens. We will conduct a representative survey before the conference to ensure an appropriate distribution of options.

What if one gets sick or has a (family) emergency just before the conference?

Tickets can be re-assigned until two days before the conference.

All on-site tickets do include remote access, so if one does not feel well one can still join remotely.

How can invoices be corrected?

Invoice details can be updated in self-service through the ticket shop.

When changes are made, the system automatically issues a credit note for the original invoice and generates a new corrected invoice.

Which ticket category should be selected?

Companies, organizational entities and freelancers are required to purchase Standard tickets — no exceptions.

To keep the conference accessible to everyone, a limited number of reduced-price tickets are offered to support education, research, and community engagement.

Reduced tickets are available for:

  • Students with a valid student ID at the time of the conference
  • Postdoctoral researchers (Post-docs)
  • Academic researchers
  • Hobbyists, enthusiasts, or those learning the language

These categories are considered company or organizational entities for ticketing purposes:

  • Start-ups
  • Public sector employees
  • Private research institutes
  • Corporate R&D departments

Do you offer any day tickets?

Yes. A limited number of day tickets are available to the public.

Availability depends on overall ticket sales and venue capacity.

Social Event tickets?

Tickets for the Social Event can be purchased as an add-on to any on-site conference ticket from day one in our ticket shop. Please note that space is limited. For day tickets, the Social Event is only available with a Wednesday Day Ticket.

What about tickets for students?

A discounted student ticket is available for anyone who holds a valid student ID at the time of the conference. The student ID must be presented upon first entry to the venue.

Please note that if student status ends before the conference takes place, the discounted ticket is not applicable.

Eligibility is limited to full-time students. We cannot accept applications from part-time students who are completing their degree alongside full-time work. Part-time jobs to support your studies do not affect eligibility.

All ticket prices include VAT

All ticket prices include 19% VAT.

The EU VAT reverse charge does not apply, as conferences are taxed in the host country. Companies may apply for a VAT refund through the local tax authorities.

Are conference T-shirts included?

A complimentary conference T-shirt is included with 3-day tickets, available by preorder only. Registration must be completed by 25 March 2026 to receive a T-shirt. Please review the available sizes before ordering.

T-shirt sizes
Can I change my T-shirt size after ordering?

You can adapt your personal information (name, contact details, etc.), but to change the T-shirt size** you need to change your order.

1. Go to your oder page, you can find the link in your oder confirmation, it looks like: https://pretix.eu/pysv/pyconde-pydata-2026/order/YOURODERID/eefnDWO7ewie/
2. Scroll to the bottom and select "Change or cancel your order → Change order" (German: "Bestellung stornieren oder umbuchen → Bestellung umbuchen")
3. Select another T-shirt size and continue to complete the change.

I’m on a budget and cannot afford a ticket.

The conference offers a Financial Aid and Scholarship Program to support those who would otherwise be unable to attend.

Please check the program page for this year’s deadlines and details.

Financial Aid Program
Is it possible for a company to purchase Individual Tickets?

No. Reduced Individual Tickets are intended for private individuals only.

Tickets purchased by a company or organization will be canceled.

Any reference to a company or organizational address in the invoice details is considered misuse and will also lead to cancellation.

I’m working with Python, but I do not get reimbursed by my employer.

In this case, it is acceptable to purchase an Individual Ticket.

Please ensure that no company or organizational information is included in the invoice details, as this would be considered misuse and may lead to cancellation.

Is it possible to purchase Student Tickets as a company?

Yes, a valid student-ID must be presented entering at the conference the first time.

I’m an academic researcher — which ticket should I choose?

Academic researchers affiliated with public academic institutions—such as public universities, or research organizations like the Max Planck or Helmholtz Institutes—are eligible to purchase an Individual Ticket.

This option is not available for researchers working in private institutes, research companies, or the public sector.

Please note that, for logistical reasons, Individual Tickets do not display institutional affiliations on conference badges. If showing your affiliation is important, consider purchasing a Standard Ticket instead.

My credit card is not working — are there alternative payment methods?

Yes. In addition to credit card payments processed via Stripe, tickets can also be paid by bank transfer through the ticket shop. Please select the bank transfer option during checkout.

All funds must be received within 10 working days and at least two weeks before the conference; unpaid tickets will be canceled automatically. If issues persist with credit card payments, please contact your bank or try again later, as temporary authorization issues can occur.

Where can I find the invoice?

After completing the purchase, all relevant information and documents, including the invoice, will be sent by email from our ticket shop Pretix. The invoice email includes a link where the invoicing address can be added or edited.

The invoicing address is often required by employers to claim VAT. Please ensure that the correct invoicing details (e.g., employer information) are entered before the conference starts. Changes to invoices cannot be made after this period.

Can tickets be resold?

Tickets are personalized and reselling is not permitted.

However, it is acceptable to purchase tickets on behalf of a friend, colleague, or subsidiary, provided proper reimbursement is handled privately.

Are badges transferable?

No, badges issued are valid only for the person to whom the badge was assigned to.

Do you have extra discounted tickets for sponsors?

Yes, please contact sponsoring.

Link to sponsoring.
How can a ticket be returned or canceled?

Tickets can be canceled until 27 March 2026 directly through the ticket shop using the self-service option provided in the confirmation email. Please follow the link in that email to manage or cancel the ticket.

If assistance is needed, the contact form below can be used. Include the full name and ticket number (e.g., TCK5-1). Refunds are exclusively issued to the same payment method used for the original purchase.

Program

How can I speak at the conference?

See the Call for Proposals for more information and the milestones above for submission deadlines. We also offer exclusive speaking opportunities to sponsors, see sponsoring.

Link to Call for Proposals
Is there a support program for speakers?

Each accepted proposal includes one complimentary conference ticket, to be used by any one speaker on that proposal. While we don’t provide speaker travel funding, financial aid is available for attendees who need support with travel and accommodation. If you’d like to be considered, please apply before the programme closes (see milestones above).

Link to Financial Aid Programme
How will the program look like?

The program will feature a mix of keynotes, talks, workshops, panels and community sessions, tailored to offer diverse perspectives and practical insights. While the final lineup will be shaped by the submissions we receive during the CfP, our goal is to create a balanced and engaging schedule that reflects the latest trends and innovations.

Check out the previous year's program here.
What about tutorials?

There will be 90-minute tutorials on conference days. The attendance is included in the ticket but seats are limited.

Can presentations be given remotely?

Remote presentations are not accepted.

All speakers are required to present their sessions on site. Absolutely no exceptions.

Are speakers invited to attend the conference?

Each accepted talk proposal includes one complimentary conference ticket for the primary speaker. Co-presenters are kindly asked to purchase their own tickets.

For accepted tutorials, up to two complimentary tickets are provided if both speakers are actively contributing to the session.

Participation in additional activities (e.g., social events) requires a separate purchase.

What happens if a ticket was purchased before receiving a free speaker ticket?

Ticket purchases will be refunded up to 27 March 2026. If a talk is accepted after that date, a refund will still be issued accordingly. Alternatively, the purchased ticket can be transferred to a colleague before the conference.

I have updated some information, but it does not appear on the website. Why?

The conference website is static and regularly synchronized with data from Pretalx. Updates may take some time to appear, so a short delay is normal.

Please note that all information updates must be made directly through Pretalx. Requests sent by email or to the helpdesk cannot be processed.

Will internet access be available during my talk?

Internet access during talks is not guaranteed. Presentations should not rely on a stable internet connection.

While efforts are made to ensure good WiFi coverage, performance may vary and cannot be guaranteed. Use of the conference network is at the speaker’s own risk.

How many speakers can be listed on a talk proposal?

A maximum of two speakers can be listed per talk proposal due to technical constraints. Please don’t add more than two speakers.

Can I add or change speakers after submitting a proposal?

Please make sure all speakers (including co-speakers) are listed on the proposal before the CFP closes. Once the CFP has closed, we can’t add or change speakers. This helps us keep the review process fair and consistent, and ensures we can confirm speaker details, scheduling, registration, and accessibility needs in time.

Lightning Talks

A lightning talk (LT) is a short presentation which must not be longer than five minutes.

You may talk about / present (almost) everything with certain boundaries:

  1. no promotion for products of companies
  2. no call for 'we are hiring' (but you may name your employer)
  3. conference or community event announcements are limited to one minute only
  4. one LT per person per conference policy
