FYI Jupyter is mentioned on Saylor in the unit 1.4 material for CS 105 Python (Assign Values to Variables) but I don’t see it in the video. Therefore, Jupyter notebook is kind of out of thin air. Also, in 1.6 String formatting, the %d %s %f are unclear (not well defined in the material) and not touched on in the live video. This is not critical … in the sense that I am fine with the course so far … but it would be nice if these were clarified.

Thank you. The next live video, on Unit 2 is tomorrow – if you’re in a position to have questions for that one, we are taking them live on the YouTube watch page, but I can also direct colleagues to check here.

I’ll pass along the feedback; it looks like the Jupyter references are just included from the source; I agree that the distinction between %d / %f / %s is not very clear.

There is an error in “The Basics of Strings” (under section1.6) of the course work. The last example will result in a syntax error. Cause: 1st parentheses not closed.

Thanks! I see it; we’ll get that fixed.

@Dr.ErikSakk how do you erase a code in unit 1. When I type the code wrongly in replit and try to erase it does not erase instead it does not allow me type anything after. How do I erase it.

I am not able to type anything. It shows the white bar.
