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.Sat, 18 Apr 2026 16:25:00 GMThttps://stackoverflow.com/questions/11487049/python-list-of-listsThe first, [:], is creating a slice (normally often used for getting just part of a list), which happens to contain the entire list, and thus is effectively a copy of the list. The second, list(), is using the actual list type constructor to create a new list which has contents equal to the first list.Sun, 19 Apr 2026 14:01:00 GMThttps://stackoverflow.com/questions/252703/what-is-the-difference-between-pythons-list-methods-append-and-extendWhat is the difference between the list methods append and extend? .append() adds its argument as a single element to the end of a list. The length of the list itself will increase by one. .extend() iterates over its argument adding each element to the list, extending the list. The length of the list will increase by however many elements were in the iterable argument. .append() The .append ...Mon, 20 Apr 2026 22:42:00 GMThttps://support.google.com/docs/answer/186103?hl=en&co=GENIE.Platform%3DDesktopCreate a dropdown list on cells with existing data In Google Sheets, open a spreadsheet.

The most popular solutions here generally only flatten one "level" of the nested list. See Flatten an irregular (arbitrarily nested) list of lists for ...Sun, 19 Apr 2026 22:58:00 GMThttps://stackoverflow.com/questions/6231973/difference-between-list-list-listt-liste-and-listobjectThe notation List<?> means "a list of something (but I'm not saying what)". Since the code in test works for any kind of object in the list, this works as a formal method parameter. Using a type parameter (like in your point 3), requires that the type parameter be declared. The Java syntax for that is to put <T> in front of the function. This is exactly analogous to declaring formal parameter ...Thu, 16 Apr 2026 15:59:00 GMThttps://stackoverflow.com/questions/2612802/how-do-i-clone-a-list-so-that-it-doesnt-change-unexpectedly-after-assignment4154 new_list = my_list doesn't actually create a second list. The assignment just copies the reference to the list, not the actual list, so both new_list and my_list refer to the same list after the assignment. To actually copy the list, you have several options: You can use the built-in list.copy() method (available since Python 3.3): CopyMon, 20 Apr 2026 16:59:00 GMThttps://stackoverflow.com/questions/509211/how-slicing-in-python-worksThe first way works for a list or a string; the second way only works for a list, because slice assignment isn't allowed for strings. Other than that I think the only difference is speed: it looks like it's a little faster the first way. Try it yourself with timeit.timeit () or preferably timeit.repeat ().Mon, 20 Apr 2026 17:49:00 GMThttps://stackoverflow.com/questions/7961363/removing-duplicates-in-listsYou 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.Sat, 18 Apr 2026 04:29:00 GMThttps://stackoverflow.com/questions/52395099/meaning-of-list-1-in-pythonI have a piece of code here that is supposed to return the least common element in a list of elements, ordered by commonality: def getSingle(arr): from collections import Counter c = Counte...Sun, 19 Apr 2026 03:02:00 GMT
