What is that needs to be coded in Python instead of C/C++ etc? I know its advantages etc. I want to know why exactly makes Python The language for people in this industry?
A few other points I've not seen in the existing answers:

it's free
it's fast [enough]
it runs on every platform I know of (AIX, HPUX, Linux, Mac OS X, Windows..)
quick to learn
large, powerful libraries 


numeric
graphical
etc

simple, consistent syntax
the existing user-base is large
because it's easy-to-learn, you don't have to be a "programmer" to use it
Why is Python a favourite among people working in animation industry?
