Learning Python

This is the repository for the LinkedIn Learning course Learning Python. The full course is available from LinkedIn Learning.

Python—the popular and highly-readable object-oriented language—is both powerful and relatively easy to learn. Whether you're new to programming or an experienced developer, this course can help you get started with Python. Joe Marini provides an overview of the installation process, basic Python syntax, and an example of how to construct and run a simple Python program. Learn to work with dates and times, read and write files, and retrieve and parse HTML, JSON, and XML data from the web.

Installing

1. To use these exercise files, you must have the following installed:
   • The latest version of Python, at least version 3.9 but preferably 3.10
   • A text editor such as Atom, Visual Studio Code, or another editor
2. Clone this repository into your local machine using the terminal (Mac), CMD or PowerShell (Windows), or a GUI tool like SourceTree.
   • You can also just download a ZIP file from Github and extract the contents to your machine.
3. Place the examples folder on your computer where they are easy to get to

Ch2 - Basics classes_finish.py

Logically speaking, a motorcycle with a sidecar has 3 wheels. Can the code be updated to "3" on line 31. Additionally line 33 will have to equal 2 self.wheels.

[Version Incompatibility]: urllib.request.urlopen(urlData) cast exceptions on Python 3.11.4

Hello Joe,

I benefit a lot from your Python course on LinkedIn. Thank you so much for such great sharing. Today, I run into one minor problem with the JSONData chapter, namely with this file:

https://github.com/LinkedInLearning/learning-python-2896241/blob/main/Ch5%20-%20Internet%20Data/jsondata_finished.py

The code runs perfectly with Python 3.9.16, but I use Python 3.11.4 for the learning purpose, then I got an error from this method urllib.request.urlopen(urlData), the terminal says:

urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1002)>

The error screenshot looks like this:

I think this should be some kind of version incompatibility issue with Python. And after some investigation, I figure out this can be resolved with a ssl context as follows:

import urllib.request
import ssl

# ...some other code logic ...
urlData = "https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_hour.geojson"

context = ssl._create_unverified_context()
webUrl = urllib.request.urlopen(urlData, context=context)

print("result code:", str(webUrl.getcode()))
# ... some other code logic ...

Not sure if this is necessary to clarify in your demo code, I presume there will be more and more software developers using Python 3.11.4 above in the future who are going to take this course since it is so popular and practical, they would run into this problem as well.

Could you please help take a look this. Thank you!
