Hi!
Iām John, in Scotland.
I suspect that I might be at the āolderā end of the spectrum of new Python users (I was 54 earlier this year 
): I have used SAS since 1999 but have finally (some might say, ridiculously late) seen the way in which the wind is blowing and have become a Python enthusiast.
With the way my adult life has worked out, I didnāt get the opportunity to finish university at the same time as my peer group through a combination of family illness, work and sheer stubbornness on my part. Iāve worked through a number of online MOOCs and this has sufficiently engaged me to apply for admission to a university MSc course in data science and artificial intelligence, as a precursor to a personal-passion-project which Iām hoping to do a PhD in, which is an āunusualā application of Bayesian search.
Any questions, please, do, feel free to message me.

Hello Dear Community Members,
I am Umer Alvi Learning Jupyter Notebook, I am at beginner level right now.
I am having issue while working with Pandas exercise
If any member can help me resolve this issue? I can share the Notebook as well if you want?

Hi all,
Nameās Florian, I tend to go by Zersiax on the web. I guess I could describe myself as a fully blind (yes really 100% fully no vision blind) developer, accessibility expert and content creator.
I build stuff, I make sure stuffās accessible and I teach others to essentially do both of those things and more, when I can. I try to primarily do that through Twitch and Youtube streams.
Given my next deep dive will be on Jupyter notebooks and friends, I decided to come say hi

Hi. Iām AndrĆ©s. Iām student of economy at UNFV (PerĆŗ) . My purpose with Jupyter is learn about How does data science work and how can it be automated? I hope to learn something of this and not die tryng.
Thank you so much to all the jupyter team!

Wanted to sign on to be able to learn something new, yeah thatās right.
Now iām unfamiliar to programming or computational stuff but, iāll manage or notā¦
I guess i just tangle on thanā¦

Hi Everyone, I am a contend creator looking at how to improve our user experience by moving to Moodle and hopefully integrate some Juypter notebooks into our lessons. It has been some time since I have used Moodle, and never as an admin, so I expect to be asking lots of questions.

Hi, my name is Andrus. I am a programmer and a big fan of Jupyter. Unlike most people, I write notebook code in Java Originally, on iJava kernel, and as of late - on JJava (GitHub - dflib/jjava: A Jupyter kernel for Java notebooks), which is a fork and a natural descendant of iJava that myself and my colleagues decided to support.
