The result, says Jupyter co-creator Brian Granger at California Polytechnic State University in San Luis Obispo, is a “computational narrative” - a document that allows researchers to supplement their code and data with analysis, hypotheses and conjecture.įor data scientists, that format can drive exploration. Instead of pasting, say, DNA gels alongside lab protocols, researchers embed code, data and text to document their computational methods. It’s just amazing.” Data explorationĬomputational notebooks are essentially laboratory notebooks for scientific computing.

Mario Jurić, an astronomer at the University of Washington in Seattle who coordinates the LSST’s data-management team, says: “I’ve never seen any migration this fast. “What this architecture helps to do is to say, you tell me where your data is, and I’ll give you a computer right there.”įor data scientists, Jupyter has emerged as a de facto standard, says Lorena Barba, a mechanical and aeronautical engineer at George Washington University in Washington DC. “In many cases, it’s much easier to move the computer to the data than the data to the computer,” says Pérez of Jupyter’s cloud-based capabilities.

In part, says Pérez, that growth is due to improvements in the web software that drives applications such as Gmail and Google Docs the maturation of scientific Python and data science and, especially, the ease with which notebooks facilitate access to remote data that might otherwise be impractical to download - such as from the LSST. One analysis of the code-sharing site GitHub counted more than 2.5 million public Jupyter notebooks in September 2018, up from 200,000 or so in 2015. This rapid uptake has been aided by an enthusiastic community of user–developers and a redesigned architecture that allows the notebook to speak dozens of programming languages - a fact reflected in its name, which was inspired, according to co-founder Fernando Pérez, by the programming languages Julia (Ju), Python (Py) and R.

Computational notebooks have been around for decades, but Jupyter in particular has exploded in popularity over the past couple of years. Jupyter is a free, open-source, interactive web tool known as a computational notebook, which researchers can use to combine software code, computational output, explanatory text and multimedia resources in a single document. And to crunch those data, astronomers will use a familiar and increasingly popular tool: the Jupyter notebook. When it comes online in 2022, the telescope will generate terabytes of data each night as it surveys the southern skies automatically. The packages I used to run the code in the book are listed in requirements.txt (Note that some of these exact version numbers may not be available on your platform: you may have to tweak them for your own use).Perched atop the Cerro Pachón ridge in the Chilean Andes is a building site that will eventually become the Large Synoptic Survey Telescope (LSST). The code in the book was tested with Python 3.5, though most (but not all) will also work correctly with Python 2.7 and other older Python versions.

The book introduces the core libraries essential for working with data in Python: particularly IPython, NumPy, Pandas, Matplotlib, Scikit-Learn, and related packages.įamiliarity with Python as a language is assumed if you need a quick introduction to the language itself, see the free companion project,Ī Whirlwind Tour of Python: it's a fast-paced introduction to the Python language aimed at researchers and scientists. The book was written and tested with Python 3.5, though other Python versions (including Python 2.7) should work in nearly all cases.
