You cannot put lists in sets since lists are mutable and could change (which could affect whether they are duplicate to another list in the set). I would suggest a different approach for a list of lists, e.g. as covered in this question about removing duplicates from a list of lists.
It is a list with six elements in it. To understand slicing better, consider that list as a set of six boxes placed together. Each box has an alphabet in it. Indexing is like dealing with the contents of box. You can check contents of any box. But you can't check the contents of multiple boxes at once. You can even replace the contents of the box.
By using a : colon in the list index, you are asking for a slice, which is always another list. In Python you can assign values to both an individual item in a list, and to a slice of the list.
How can I check if a list has any duplicates and return a new list without duplicates?
(The list object must be iterable, implied by the for..in stanza.) The lesson here for new programmers is: You can’t get the number of items in a list without counting them at some point. The question becomes: when is a good time to count them?
In Python 2, print is a statement, which is a whole different kind of thing from a variable or function. Statements are not Python objects that can be passed to type(); they're just part of the language itself, even more so than built-in functions.

Print, scan, and copy by clicking the HP App home screen tiles. You can also check printer status, troubleshoot issues, order supplies, and set printer preferences.
This print statement simply prints (3.0, 4.0), i.e. the values in blank.x and blank.y. I don't understand the % operator in front of the (blank.x, blank.y) in the last line. What does it do and where can I find it in the documentation? Googling this, I always end up with the modulus operator.
If your printer can successfully print a test page but fails to print other documents, it usually suggests there might be an issue with the print job settings, the file you're trying to print, or the printer driver.
To lighten or darken the print output on your HP LaserJet Pro MFP M148fdw, you can adjust the print density settings. Here's how to do it: Method 1: Using the Printer's Control Panel On the printer's Home screen, press the Setup button (gear icon). Navigate to System Setup > Print Quality. Select Adjust Density.

When reading, list is a reference to the original list, and list[:] shallow-copies the list. When assigning, list (re)binds the name and list[:] slice-assigns, replacing what was previously in the list. Also, don't use list as a name since it shadows the built-in.
The second, list(), is using the actual list type constructor to create a new list which has contents equal to the first list. (I didn't use it in the first example because you were overwriting that name in your code - which is a good example of why you don't want to do that!)
My question is in the significance of the -1 in return c.most_common()[-1]. Changing this value to any other breaks the code as the least common element is no longer returned. So, what does the -1 mean in this context?
