I recently decided to try my hand at making an auto-load extension for Python and Plumbum. I was planning to suggest it as a new feature, then I thought it might be an experimental feature, and now it’s just a blog post. But it was an interesting idea and didn’t seem to be well documented process on the web. So, here it is.
The plan was to make commands like this:
[Read More]Wouldn’t it be nice if we had uncertainty with a nice notation in IPython? The current method would be to use raw Python,
from uncertainties import ufloat
print(ufloat(12.34, 0.01))
12.340+/-0.010
Let’s use the infix library to make the notation easier. We’ll define |pm| to
mean +/-.
I’ve been working on a color addition to Plumbum for a little while, and I’d
like to share the basics of using it with you now. This library was originally
built around a special str subclass, but now is built on the new Styles
representation and is far more powerful than the first implementation. It safely
does nothing if you do not have a color-compatible systems (posix + tty
currently), but can be forced if need be. It is included with Plumbum, so you
don’t have to add a requirement for your scripts that is non-essential (as color
often is). It is integrated with plumbum.cli, too. Also, I’ve managed to
accelerate the color selection algorithms about 8x, allowing near game-like
speeds. (see the fullcolor.py example).
