hello world

Hello,
When starting the first program I have this message showing in red in the IDLE and I have no message in minecraft:

Traceback (most recent call last):
  File "C:/Users/cai/Desktop/AdventuresInMinecraft-PC/MyAdventures/BonjourMondeDeMinecraft.py", line 3, in <module>
    mc.postToChat ("Bonjour le monde de Minecraft")

    if isinstance(e, collections.Iterable) and not isinstance(e, str):
AttributeError: module 'collections' has no attribute 'Iterable'

I am on Windows 10 PC and under minecraft 1.12
Thanks in advance for your help as I don't understand the error message.
Have a good day

It looks like you are using the starter kits from the 2nd edition of the book? e.g. downloaded from https://adventuresinminecraft.github.io/

Are you using Python 3.10? I noticed recently that there was an incompatibility issue when Python 3.10 was released and released new versions of the Starter Kits.
