Why Python (a bit different)

[Gerald Senarclens de Grancy]

Hi everybody!
I recently gave a little lecture to my collegues at University and 
couldn't answer a nontechnical question of my prof afterwards. He wanted 
to know 'why python', but not in the way 'Why should so. use Python?', 
but meaning 'Why did Guido create Python?'.
I couldn't find a good ressource online yet, maybe so can give me a good 
link or just the straightforward answer.
Thanks, Gerald
