The second, list(), is using the actual list type constructor to create a new list which has contents equal to the first list. Let summarize the differences between list.of and arrays.aslist list.of can be best used when data set is less and unchanged, while arrays.aslist can be used best in case of large and dynamic data set. 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 most popular solutions here generally only flatten one level of the nested list See flatten an irregular (arbitrarily nested) list of lists for solutions that.
Don't use quotes on the command line 1 don't use type=list, as it will return a list of lists this happens because under the hood argparse uses the value of type to coerce each individual given argument you your chosen type, not the aggregate of all arguments You can use type=int (or whatever) to get a list of ints (or whatever) I can not find tge list of account passwords tgat i saved in google account In c# if i have a list of type bool What is the fastest way to determine if the list contains a true value I don’t need to know how many or where the true value is
How can i list all files of a directory in python and add them to a list? I'm looking for a quick way to create a list of values in c# In java i frequently use the snippet below: I want to get a list of the column headers from a pandas dataframe The dataframe will come from user input, so i won't know how many columns there will be or what they will be called The list is the part of python's syntax so it doesn't need to be declared whereas you have to declare the array before using it

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. Leaving any blank puts them at a default value, in your case it is taking every y elements starting at x and going until the end of the list (double colon) in python when subscripting sequences? Reorder list items on your computer, go to google keep Point to the item you want to move
At the left, click and hold move Drag the item where you want. 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 Other than that i think the only difference is speed It looks like it's a little faster the first way
To_list () is a method of pandas dataframes that returns a list representation of the dataframe Although both methods return the same output, their differences lie in their origins and compatibility 67 if i have a list of lists and just want to manipulate an individual item in that list, how would i go about doing that List1 = [[10,13,17],[3,5,1],[13,11,12]] what if i want to take a value (say 50) and look just at the first sublist in list1, and subtract 10 (the first value), then add 13, then subtract 17?
