static PyThread_type_lock interpreter_lock = 0; /* This is the GIL */ This line of code is in ceval.c, in the CPython 2.7 interpreter’s source code. Guido van Rossum’s comment, “This is the GIL,” was added in 2003, but the lock itself dates from his first multithreaded Python interpreter in 1994. On Unix systems, PyThread_type_lock is an alias for the standard C lock, mutex_t. It is initialized when the Python interpreter begins:

concurrent programming is hard and while coroutines allow us to avoid callback hell it can only get you so far, you still need to think about creating tasks, retrieving results and graceful handling of errors. Sad face. Good news is all of that is possible in asyncio. Bad news is it’s not always immediately obvious what wrong and how to fix it. Here are a few patterns I’ve noticed while working with asyncio.

The Single Responsibility Principle (SRP) is an effective strategy against this sort of problem by reducing the amount of code in the several layers of your codebase, focusing each one on specific objectives and separating them by logical domain.

Poet helps you declare, manage and install dependencies of Python projects, ensuring you have the right stack everywhere. The package is highly experimental at the moment so expect things to change and break. However, if you feel adventurous I'd gladly appreciate feedback and pull requests.

I’ve been working on a Python module called Sofi that generates user interfaces. It can deliver a desktop feel while using standard single-page web technologies. For flexibility, I designed it to work through two methods of distribution: in-browser and executable.
