In the field, Python stays mostly simple. All those stuff are optional, and they are used in this spirit.

In fact, most Python code I see out there seldom even use lambdas, comprehension lists or yield.

You gotta remember a huge part of the Python user base are not programmers, and they don't have the time to figure those things out.

That's one of the reason of Python success: it scales up, and it scales down.
