no display name and no $DISPLAY environment variable in Jupyter Notebook

[fissehab]

I want to teach Python for kids. I want them to use Jupyter Notebook. To avoid the hassle of installation, I want them to use a free online Jupyter Notebook. I thought google's colab (link and jupyter.org (link could be best solutions. However, I tried them both and got the error message below:

from turtle import *
colors = ['red', 'purple', 'blue', 'green', 'yellow', 'orange']
for x in range(360):
 pencolor(colors[x % 6])
 width(x / 100 + 1)
 forward(x)
 left(59)

TclError: no display name and no $DISPLAY environment variable

@fissehab I tried Jupyter as well and got the same error. In my high school classes, we use trinket.io and repl.it. Both of those are free online Python IDEs that will "avoid the hassle of installation".

Here is your above code running in Trinket and here it is in Repl.it

Finally, I also want to recommend the Mu IDE. It requires download, but my students were able to install it without needing an administrator password. Mu is very user friendly and was designed by educators for students.

My son uses the turtle Python package with a Jupyter Notebook installed in his machine and it works fine for him and that is why I was looking for free online Jupyter Notebook. However, what you have suggested are what I should use now. Thank you very much!
