What does Python offer?

[Solosnake]

Hello

I have beome curious about Python after playing a game called 'Severance -
Blade of Darkness', which uses python scripts. I know very little about the
language. I am a C++ programmer, and would like to ask the Python community
:

What is unique or special about Python?
Why would it be useful to a games programmer?
Could it be used for allowing users to customize games, eg reprogramming AI
bots etc?

Thanks for all answers
