xlines

x lines of Python

An Agile blog series exploring common geosciencey workflows in x lines, where ideally x ≤ 10 but not necessarily, I haven't thought it through properly yet. These will be Jupyter Notebooks running on binder.

Click the launch binder button to start the interactive notebooks.

Terms of engagement

• One line per English-language sentence.
• No semi-colons or line continuation.
• Lines can be broken for readability, especially sequence items, or function arguments.
• import statements and comments don't count. I'm really interested in the bits of code that do the thing, whatever that is.
• But we can only import libraries on conda-forge or PyPi.
• Plotting and other kinds of inspection don't count, unless they're central to the point of the code. They're more just for seeing what you're doing.

Running the notebooks

Hopefully you're already using Anaconda. To make an environment for this notebook, and install obspy, you can do this:

# Make the environment
conda create -n xlines anaconda Python=3.5

# Start it
source activate xlines

# Install obspy and bruges
conda config --add channels conda-forge
conda install obspy
pip install bruges

# cd to directory with the notebook in it, then
jupyter notebook

Technical notes to self

Or to others wanting to set up binders. If you found a way around these problems, I'd love to know about it!

• The file environment.yml should be minimalist. The output of conda env export did not work for me.
• You can avoid users having to answer a question about kernels by replacing the kernelspec in the notebook JSON with this:

    "kernelspec": {
      "display_name": "Python [conda env:binder]",
      "language": "python",
      "name": "conda-env-binder-py"
    }
