Python videos | Python Part 9 - Files and Folders
Posted by Andy Brown on 16 October 2021
Python makes reading and writing files and looping over files and folders a joys, as this tutorial (which includes a long worked example towards the end) hopefully will demonstrate!
This video has the following accompanying files:
|Useful links.txt||Text file||Useful web links referenced|
|Best films ever.txt||Text file||List of best films to read in|
|Read in films.py||Python code||Program to read in list of films|
|Write out films.py||Python code||Program to write out worst films|
|Looping over files.py||Python code||Program to loop over files and folders|
|Listing contents of 3 files.py||Python code||Program to loop over and read in 3 files|
|1 - countries 1-10.csv||CSV file||CSV files containing countries - part 1|
|2 - countries 11-20.csv||CSV file||CSV files containing countries - part 2|
|3 - Countries 21-30.csv||CSV file||CSV files containing countries - part 3|
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.
