Python videos | Python Part 7b - Sequences: slicing
Posted by Andy Brown on 14 October 2021
The previous tutorial in this series looked at looping over all of the elements of a sequence, but there are a number of tricks that you can use to pick out just a subset of the elements in a list, tuple, range of numbers or string, using a technique called slicing, as explained in this tutorial.
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:
|Base data.py||Python code||Tuple of films and string quotation|
|Simple slicing.py||Python code||Some simple slicing examples|
|Editing lists.py||Python code||Changing the contents of lists|
|Step values.py||Python code||Using step values|
Click to download a zipped copy of the above files.
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.
