Once you have opened a project, you are ready to create a file.
If your project isn't upgraded, you will get a red banner warning that your project is running on a trial server. Ignore the warning for now and keep going.
Click (+) New and enter example where it says, Name your file.... Select Jupyter notebook to set the file type. Clicking a button for the type of file causes the file extension to be added automatically.
Select the "Python 3 (system-wide)" kernel.
Now enter a line of python code in the first cell of the notebook:
print("hello")
And click Run or press Shift-Enter to run the code.
You have used CoCalc's two main toolbars a bit during your first session. Learn more about them at these locations in this online guide:
.. index:: Member Hosting;compute session
CoCalc will keep track of projects you have open and files that are open within those projects. When you return, you will see the same open projects and files. In addition, if you have a program running and disconnect, it will keep running, with a few exceptions: the program will stop if any of the following occurs:
- your project is on a trial server (i.e. does not have Member Hosting upgrade applied) and the server is restarted
- you do not edit a file for more than the idle time specified in Project Settings
- the program crashes or runs out of memory
