Python videos | Python Part 21a - Programming using classes
Posted by Andy Brown on 26 January 2022
Like most other modern programming languages, Python encourages you to code using classes (it's called object-orientated programming). This tutorial will teach you using a practical example about objects, attributes or properties, methods, instantiation and much more besides!
If you're not a channel member, don't worry - the video will be released publicly after a short period of member exclusivity.
This video has the following accompanying files:
|Attributes.py||Python code||Instance attributes|
|Pets.txt||Text file||List of pets|
|Methods.py||Python code||Writing class methods|
|Managed attributes - base code.py||Python code||Template program for read/write properties|
|Managed attributes.py||Python code||Final read/write properties|
|Dunder methods.py||Python code||Documentation (__str__ and __doc__)|
|Existing classes.py||Python code||All objects in Python use classes|
Click to download a zipped copy of the above files.
There are no exercises for this video.
Making a video bigger
You can increase the size of your video to make it fill the screen like this:
Play your video (the icons shown won't appear until you do), then click on the full screen icon which appears as shown at its bottom right-hand corner.
When you've finished viewing a video in full screen mode, just press the Esc key to return to normal view.
Improving the quality of a video
To improve the quality of a video, first click on the Settings icon:
Make sure you're playing your video so that the icons shown appear, then click on this gear icon at the bottom right-hand corner.
Choose to change the video quality:
Click on Quality as shown to bring up the submenu.
The higher the number you choose, the better will be your video quality (but the slower the connection speed):
Don't choose the HD option unless you have a fast enough connection speed to support it!
Is your Wise Owl speaking too slowly (or too quickly)? You can also use the Settings menu above to change your playback speed.
