IDE for High School Data Science Class

I am teaching a (pilot) high school data science class. I have access to Google Sheets and CODAP, but would really like to use Python and teach at least a little programming. My problem is I cannot use kaggle or Google Colab. I am looking for a free IDE that might not be blocked by my firewalls. My students use little Chromebooks.

There was a thread about installing Python on Chromebooks here:

I don’t know anything about Chromebooks but usually if you have Python installed you have IDLE which is probably a suitable IDE for your students.
