"The trick on how to do this is to try and open the file once it arrives in ‘append’ mode. This will fail if another process is using the file. So what we can do in this case is then keep trying to open it in append mode until it’s successful and at that point we know that there is no longer a lock on the file.
Sounds a bit hacky but we couldn’t think of a more elegant way to do it." -

"wanted to generate RSS 2.0 feeds in Python. Nothing fancy but for certain tasks I needed it something that is quick and just works out of the box. I found rfeed – a library to generate RSS 2.0 feeds in Python. It is in my opinion straightforward to use."

"The argparse module makes it easy to write user-friendly command-line interfaces. The program defines what arguments it requires, and argparse will figure out how to parse those out of sys.argv. The argparse module also automatically generates help and usage messages and issues errors when users give the program invalid arguments."

"
What is it?
SimpleCV is an open source framework for building computer vision applications. With it, you get access to several high-powered computer vision libraries such as OpenCV – without having to first learn about bit depths, file formats, color spaces, buffer management, eigenvalues, or matrix versus bitmap storage. This is computer vision made easy." -

"Most of the current formatters for Python --- e.g., autopep8, and pep8ify --- are made to remove lint errors from code. This has some obvious limitations. For instance, code that conforms to the PEP 8 guidelines may not be reformatted. But it doesn't mean that the code looks good.
YAPF takes a different approach. It's based off of 'clang-format', developed by Daniel Jasper. In essence, the algorithm takes the code and reformats it to the best formatting that conforms to the style guide, even if the original code didn't violate the style guide. The idea is also similar to the 'gofmt' tool for the Go programming language: end all holy wars about formatting - if the whole codebase of a project is simply piped through YAPF whenever modifications are made, the style remains consistent throughout the project and there's no point arguing about style in every code review.
The ultimate goal is that the code YAPF produces is as good as the code that a programmer would write if they were following the style guide. It takes away some of the drudgery of maintaining your code." -

"Substance D is an application server built using the Pyramid web framework. It can be used as a base to build a general-purpose web application like a blog, a shopping cart application, a scheduling application, or any other web app that requires both an administration and a retail interface.
Substance D owes much of its spirit to the Zope application server.
It requires Python 2.7, 3.4, or 3.5." -

"Tkinter is Python's de-facto standard GUI (Graphical User Interface) package. It is a thin object-oriented layer on top of Tcl/Tk. "
