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

Did you look at this issue:

ipython notebook - $DISPLAY variable error

Your problem might be solved if you run before: 

%matplotlib inline
