News and Important info

This is a medium-advanced course in Python tools such as NumPy, SciPy, Matplotlib, and Pandas. It is suitable for people who know basic Python and want to know some internals and important libraries for science - basically, how a typical scientist actually uses Python. Read the learner personas to see if the course is right for you. Prerequisites include basic programming in Python.

Part of Scientific Computing in Practice lecture series at Aalto University, in partnership with CodeRefinery.


This course is hosted by Aalto Scientific Computing (Aalto University, Finland) and CodeRefinery. Our livestream, registration, materials, and published videos are free for all in the spirit of open science and education, but certain partners provide extra benefits for their own audience.

Practical information

This is an online course streamed via Twitch (the CodeRefinery channel) so that anyone may follow along without registration. You do not need a Twitch account. There is a collaborative notes link which is used for asking questions during the course. The actual material is here.

While the stream is available even without providing personal data, if you register you may get collaborative notes access for asking questions and will support our funding by contributing to our attendance statistics.


It is possible to obtain a certificate from the course with a little extra work. The certificate is equivalent to 1 ECTS and your study supervisor will be able to register it as a credit in your university study credit system. Please make sure that your supervisor/study program accepts it.

Learners with a valid Aalto student number will automatically get the credit registered in Aalto systems.

To obtain a certificate/credit, we expect you to have registered to the course by 10/11/2023, follow the 4 sessions and provide us with at least the following 5 documents via email (1 text document, 4 or more python scripts/notebooks). Please remember to add your name and surname to all submitted files. If you are a student at Aalto University, please also add your student number.

  • 1 text document (PDF or txt or anything for text): For each of the 4 days, write a short paragraph (learning diary) to highlight your personal reflections about what you have found useful, which topic inspired you to go deeper, and more in general what you liked and what could be improved.

  • 4 (or more) .py scripts/notebooks: For each of the 4 days take one code example from the course materials and make sure you can run it locally as a “.py” script or as a jupyter notebook. Modify it a bit according to what inspires you: adding more comments, testing the code with different inputs, expanding it with something related to your field of research. There is no right or wrong way of doing this, but please submit a python script/notebook that we are eventually able to run and test on our local computers.

These 5 (or more) documents should be sent before 31/December/2023 23:59CET to If the evaluation criteria are met for each of the 5 (or more) documents, you will receive a certificate by mid January 2023. Please note that we do not track course attendance and if you missed one session, recordings will be available on Twitch immediately after the streaming ends.

NEW! Credit fast track: if you submit your homework by 17/November/2023 23:59CET, you get the credit/certificate before 30/Nov. If you submit after the 17/Nov deadline, your credit/certificate will be processed in January (see previous paragraph).

Community standards

This is a large course, and we will have many diverse groups attending it. There will be people attending at all different levels, from “just learned Python” to “been using Python for a while and want to see some tips and tricks”. Everyone will choose their own path, some people will be more hands-on or more “watching”. Everyone is be both a teacher and a learner. Even our instructors are always learning things and make mistakes (and this is part of the point!). Please learn from our mistakes, too!

This course consists of both lectures, hands-on exercises, and demos. It is designed to have a range of basic to advanced topics: there should be something for everyone.

The main point this course is the exercises. If you are with a group, we hope people to work together and help each other. We expect everyone to help each other as best as they can with respect for different levels of knowledge - at the same time be aware of your own limitations. No one is better than anyone else, we just have different existing skills and backgrounds.

If there is anything wrong, tell us - HackMD is best. If you need to contact us privately, you can message the host on Zoom, instructor chat is via CodeRefinery chat, and by email contact CodeRefinery support. This could be as simple as “speak louder / text on screen is unreadable” or someone is creating a harmful learning environment.
