I'm working with Python, but I do NOT get reimbursed by my employer.

It's ok to buy an individual ticket.

I'm an academic researcher, which one is the right ticket for me?

As an academic researcher affiliated with a public academic institution, such as public universities or Max Planck and Helmholtz Institutes, you are eligible to purchase an Individual Ticket. However, this option is not available to those working in private institutes, research companies, or the public sector. Additionally, it's important to be aware that nIndividual tickets, due to logistical reasons, won't display your affiliation on your badge. If having your affiliation shown is important to you, you should consider purchasing a business ticket instead.
