Python Intro Day 1

This post is the first in a two-part series of introductory python talks for the start of the semester. The majority of this talk is based on Software Capentry’s Python Notice Inflammation lesson.

Watch the recording of the presentation here. Presentation by Sarah Murphy (sarah.y.murphy@wsu.edu). Data used in this lesson can be downloaded here. We will use the inflammation-01.csv file in the Data folder for this lesson.

Some vocabulary

Library - Families of code. You can import these to give you extra tools
Variable - A value with a name assigned to it.
Function - A named group of code. Can be imported by itself or with a library.
Arguments/Parameters - Variables or values given to a function.

Getting Python on your computer

Download Python on it's own (https://www.python.org/downloads/
I use Anaconda: https://www.anaconda.com/. This comes with Jupyter Notebook and Spyder. It also comes with a library manager (conda).

weight_kg = 60

# Defining variables
## Includes letters, digits, and underscores
## Case sensitive
## 0weight, 1weight doesnt work, can't start with a number


# floating point number
floatingnumber = 60.2
floatingnumber_2 = 60.0

# integer
integernumber = 60

# strings
stringnumber = '20'

weight_lb = 2.2 * weight_kg

print('The weight in kg is ', weight_kg)

print(type(weight_kg))

print(type(stringnumber))


import numpy

text_file = numpy.loadtxt(fname = '/Users/smurphy/swc-python/data/inflammation-01.csv',
              delimiter = ',')

import matplotlib.pyplot as plt

plt.plot(text_file[:,0])

The figure created by the code above using the inflammation-01.csv dataset.
