Python videos | Python Part 19 - Pandas
Posted by Andy Brown on 12 November 2021
This tutorial explains what pandas is and does, including creating dataframes, importing data into them from CSV files, Excel workbooks and SQL Server tables, indexing dataframes, showing statistics and much more besides!
See our full range of Python training resources, or test your knowledge of Python with one of our Python skills assessment tests.

After watching this video, you may like to test your understanding by doing one or more of the following exercises:
Exercise | Level |
---|---|
Read an Excel workbook into a Pandas dataframe, then perform various operations | Standard |
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.
