Code Snippets Extension for JupyterLab

Jupyter Lab Menu Extensions

---

The idea of the Snippet Library is to create a tool for rapid prototyping with the aim of quickly and easily developing data analysis workflows. It adds a customizable menu to the Jupyter notebooks to insert code snippets, code examples and boilerplate code.

This Jupyter Lab extension is based on the jupyterlab-snippets extension. How do I read a csv file? There´s a snippet for that. How do I visualize missing values in a pandas dataframe? There´s a snippet for that. How do I plot the correlation matrix of my pandas dataframe (and make it look good)?. There's a snippet for that. You get the idea.

Focus of the provided snippets is helping to get started (or to get more productive) on data science tasks. The menu provides several snippets ordered by typical task groups used for exploring and visualizing data.

The default menu provides the items:

• Data which provides snippets to read, write and transform data.

• Modelling which provides snippets to train ML models (mostly based on sklearn). You'll find examples for classification, regression and clustering.

• Plotting which provides some regularly used snippets for matplotlib, bokeh and the pandas interface.

• Utils which provides some snippets which do not fit into the former categories but are still helpful.

With the jupyter extension a set of base snippets are provided, for which we are mostly sure, that they do their job as described. Also, it's also possible to add your own snippets, either by copy-pasting them or by uploadling them from a python file.

Configuration

The follwoing Prerequisites must be installed:

Anaconda

Jupyterlab 2.X

(Python 3.X)

After installation enter the following in the three lines in the command line (Anaconda Prompt for Windows):

jupyter lab build

Install via Make (Linux)

git clone https://github.com/fraunhofer-iais/IAIS-JupyterLab-Snippets-Extension.git

cd snippetlib_jl

git checkout master

make install

Operating instructions

Start Jupyter Notebook

• Windows: Open Anaconda prompt and type "jupyter notebook".

• Linux: Open terminal and type "jupyter notebook“.

• The Jupyter front-end should open in a browser window.

How to add your own snippets

To upload a new snippet on the jupyter notebook,paste the following in a new cell.

from snippetlib_jl import upload_snippet as us

upload_snippets = us.Upload_Snippet()

Refresh the page and on the Snippets menu you should see the newly added snippet.

To create new snippets,on the jupyter notebook,paste the following in a new cell.

from snippetlib_jl import paste_snippet as ps

paste_snippets = ps.Paste_Snippet()

Refresh the page and on the Snippets menu you should see the newly added snippet.
