Materials for the LambdaConf tutorial, "A Functional Programming approach to data processing in Python". Presentation slides can be found at https://speakerdeck.com/reubano/a-functional-programming-approach-to-data-processing-in-python

Preparation

This is an interactive (hands-on) tutorial. As such, you can choose to follow along locally on your laptop, or remotely in a binder notebook.

Local

Clone this repo

git clone https://github.com/reubano/lambdaconf-tutorial.git
cd lambdaconf-tutorial

Make sure you have a recent version of Python 3 and pip 3

# follow directions for your platform from the above link above

python3 --version
# Python 3.6.1

pip3 install --upgrade pip
pip3 --version
# pip 9.0.1 from ...

(Optional) Setup and activate a virtual environment

pip3 install virtualenv
virtualenv lambdaconf-tutorial
source lambdaconf-tutorial/bin/activate

(Optional) install iPython, an enhanced Python shell

# if you are working in a virtualenv
pip install ipython

# if you are *not* in a virtualenv
pip3 install --user ipython

Install the packages to be used during the workshop

# if you are working in a virtualenv
pip install riko==0.51.0

# if you are *not* in a virtualenv
pip3 install --user riko==0.51.0

Start the interactive Python

# if you installed iPython
ipython

# if you did *not* install iPython
python3

You should now be in an interactive shell that looks something like this:

Python 3.6.1 (default, May 24 2017, 01:02:17)
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>

In this interactive shell, you can enter any valid Python and immediately see the result.

>>> 1 + 3
4
>>> x = 1 + 3
>>> x
4

To play around with the code, view the following files in your text editor of your choice.

• Presentation: use to follow along as I talk, and reference during the exercises
• Exercises: test your own code by typing python3 exercises.py in the terminal (NOT a python shell)
• Solutions: see how the solution should look by typing python3 solutions.py in the terminal (NOT a python shell)

Remote

To play around with the code, visit mybinder and select the appropriate notebook.

• Presentation (presentation.ipynb): use to follow along as I talk, and reference during the exercises
• Exercises (exercises.ipynb): test your own code by typing directly into your browser
• Solutions (solution.ipynb): interact with the solution and view the intermediate results

A few tips
