I agree with the response that there are a few "gotchas" with python, like with any language! I have gotten caught up with a few type problems when dealing with sending raw binary data over serial and things like that - but luckily python has great unit testing frameworks to help with this.
My main beef with python is that it is harder to deploy projects to other people, without them setting up a virtual environment or things like that. I know that there are some tools to help compile but they aren't easy to use.
Also, it is hard to create GUI applications vs languages like C#!
Other than that I love using python and I think it is a great tool to use in embedded development along with c/c++.
As far as deployment goes, we've had good luck with pex files (executable zip files containing everything but the interpreter). https://github.com/pantsbuild/pex. Your deployment target still needs the right version of the Python interpreter and .so files that your dependencies might link against.
Personally, I've found that Go solves most/all Python issues without introducing too many of its own--and anyone writing Python (sans mypy) doesn't get to chastise Go for lacking generics! :)
