Thanks for the Article but I got an error :
TypeError: 'function' object is not iterable

TypeError: 'function' object is not iterable
Change the function name from frames to renderFrames in line 40 and 50.

name 'clear_output' is not defined
Use from IPython.display import clear_output if you're using Jupyter notebook.

subsr97 - You must add in line 3 of your code
from IPython.display import clear_output

Looks like Author has not defined the Solution on How to resolve the TypeError: function object is not iterable.
If message thread is Open then please provide the response on the Error Resolution. Appreciation in advance!

print(frame['frame'].getvalue())
AttributeError: 'str' object has no attribute 'getvalue'

print(frame['frame'])
should work
