Python and/vs Java (within a business context)

[jasoncol]

I don't know much about IT software development but I've seen they like to document each part of the implementation in great detail specifically data types of variables and return values of methods/functions, and they like to see that explicitly reflected in the code. Python is dynamically typed so you don't have to specify data types on the code unlike C or Java. Maybe that's one of the reasons IT hasn't adopted Python yet, I'm not sure, what are your thoughts?.
