This doc intends to provide basic understanding / skill to use the Python Debugger (PDB).
There's certainly more to the debugger than what's below. This just provides quick and dirty info.
Open a terminal / command line and navigate to the directory containing the main file you want to debug.
This short tutorial is related to lesson one of UW's PCE Python 220 - Summer 2019.
If you're experiencing a error like ModuleNotFoundError: No module named ..., then follow try one of the two options below.
Basically, you have to tell Python the folder path for where the tests will run using by setting the PYTHONPATH environment variable.
You can do this while running your tests.
This is the "Iris" dataset. Originally published at UCI Machine Learning Repository: Iris Data Set, this small dataset from 1936 is often used for testing out machine learning algorithms and visualizations (for example, Scatter Plot). Each row of the table represents an iris flower, including its species and dimensions of its botanical parts, sepal and petal, in centimeters.
The HTML page provides the basic code required to load the data and display it on the page (as JSON) using D3.js.
