It sounds like you're incredibly picky. I moved away from Ruby to Python years ago for 99.9% of my professional work. Ruby to me is write once read nowhere. "Professional" developers invent all sorts of creative DSLs to make code impossible to use. Rails is insufficient for a project of modest complexity owing once again to it's 9 levels of hell worth of DSLs. If you follow the prescribed formulas exactly, to the letter, and never stray from the DSLs given in Rails, and Ruby code in general, is fantastic. Once you start to stray you end up in hell.

Python has it's faults. Most are handled by a good editor. I only switch from Python when I need something lower level. With Python a company gains:

1. Simple language with relatively low ramp-up time

2. Reasonably fast with proper tuning. I've been on projects processing impressive numbers of RPS built entirely in Python.

3. Comprehensions. You claim they are not sufficient. With them I rarely need to lambda anything. When I do I have `functools` to do any other work.

4. A massive ecosystem of libraries, resources, etc.

A company loses:

1. Projects become difficult to understand at a certain size. This is not properly addressed by even the proper use of MyPy.

2. Somewhat more involved testing process compared to it's contemporary - Ruby.

To compare apples-to-apples you can even look at the interpreters themselves. Python's mainline interpreter has been able to run CIRCLES around Ruby's for years now. I can understand using something like Go for systems level work, but there are few languages that give you so much for very little investment. Even dropbox was run entirely on Python for LONG time before it became too unruly. That's INCREDIBLE given the simplicity of the language.

What you use on your personal time is irrelevant. Your complaints apparently are not experienced by the swathes of companies switching from almost every language under the sun to Python. It's here to stay. At least until Go's ecosystem catches up to Python's. My belief is Go will be the only language to unseat Python at this point. Python will still be around as a "perl-replacement" for basically ever as far as I am concerned.
