Python Study Group

What is it?
The Python Study Group is an opportunity to learn, teach and discuss Python with your fellow edXers! Meetings occur once every three weeks and are listed on the engineering calendar.
How does it work?
Usually, a single presenter will put together a talk on a topic of their choosing. It can be anything related to python, including particular libraries or edX-specific patterns and usages. Sometimes we vary the format with things like
Group code reviews
Helping someone with a personal project
Roundtable
AMAs with some of our experts
We are also actively looking to expand the different types of study group meetings, so if you have an idea please ping the group runner (currently @Rebecca Graber (Deactivated) ) on slack.
Who can present?
Newbies, experts, and everyone in between. We especially encourage folks who are newer to python to present, as there is no better way to learn a topic than to teach others. We have also had presentations of the form ‘please help me with this thing I don’t understand,' where one person picked the brain of the assembly on a topic they were struggling with.
Tell me more about presenting
We have put together a handy guide to presenting at PSG: https://openedx.atlassian.net/wiki/spaces/AC/pages/2856158322 . If you are interested in presenting, please reach out to @Rebecca Graber (Deactivated) in Slack.
Schedule:
Some links are still in the process of being migrated as part of the Google docs migration
Most recent event should be at the top of the table.
