Python videos | Python Part 12a - Functions
Posted by Andy Brown on 25 October 2021
Instead of writing your code in a single long file you can (and should) call separate functions to handle discrete tasks. In addition to all the modules supplied by third parties, this tutorial shows you how to create your own libraries of useful functions.
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:
|Action.csv||CSV file||CSV file of action films|
|Animation.csv||CSV file||CSV file of animation films|
|Comedy.csv||CSV file||CSV file of comedy films|
|Musical.csv||CSV file||CSV file of musicals films|
|Science fiction.csv||CSV file||CSV file of science fiction films|
|Get duration function.py||Python code||Get film duration in human readable format|
|Read CSV file.py||Python code||Read in a CSV file of films|
|Get film age.py||Python code||Get the age of a film|
|WOL_functions.py||Python code||Module containing all functions written|
|Complete example.py||Python code||Bringing all other functions together|
|Doc strings.py||Python code||Example of document strings|

After watching this video, you may like to test your understanding by doing one or more of the following exercises:
You can also download the answers to each exercise from the links above.
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.
