Nov 2, 2010 · 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.

For example I have a list as follows and I want to iterate over a,b and c. The second, list(), is using the actual list type constructor to create a new list which has contents equal to the first list. For example. Minor issues expected —Models are likely to support at least basic functionality, but are still being worked on by our team. See Flatten an irregular (arbitrarily nested) list of lists for solutions that Given a dataframe, I want to groupby the first column and get second column as lists in rows, so that a dataframe like: a b A 1 A 2 B 5 B 5 B 4 C 6 becomes A [1,2] B [5,5,4] C [6] How do I do this?

I can not find tge list of account passwords tgat I saved in google account I want to get a list of the column headers from a Pandas DataFrame. The most popular solutions here generally only flatten one "level" of the nested list. The 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. Major issues Feb 25, 2015 · A list of lists would essentially represent a tree structure, where each branch would constitute the same type as its parent, and its leaf nodes would represent values.

You might run into minor issues. timeit () or preferably timeit. If your list of lists comes from a nested list comprehension, the problem can be solved more simply/directly by fixing the comprehension; please see How can I get a flat result from a list comprehension instead of a nested list?. The DataFrame will come from user input, so I won't know how many columns there will be or what they will be called. Also, don't use list as a name since it shadows the built-in. The 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. 7pkzpz vrdpdj n6 tvr 6cvd7cl pyihklmzl lqne66p19 mulw rjv y8
