As Already explained you are setting the second element using the result of comparing to a list which returns True/1 as bool is a subclass of int. You have a list not a numpy array so you need to iterate over it if you want to change it which you can do with a list comprehension … Read more
If you had a List<List<Integer>> then you’d be able to add a LinkedList<Integer> to it. But you can’t do this for an ArrayList<ArrayList<Integer>>, so the latter can’t possibly be a type of List<List<Integer>>.
As you discovered, np.array tries to create a 2d array when given something like You have apply some tricks to get around this default behavior. One is to make the sublists variable in length. It can’t make a 2d array from these, so it resorts to the object array: And you can then append values … Read more
The issue is just as the error indicates, time_list is a normal python list, and hence you cannot index it using another list (unless the other list is an array with single element). Example – If you want to do that kind of indexing, you would need to make time_list a numpy.array. Example – Another … Read more
What this does is calculate the longest data entry to determine the column width, then use .ljust() to add the necessary padding when printing out each column.
string.Split() returns an array – you can convert it to a list using ToList(): Note that you need to import System.Linq to access the .ToList() function.
Your solution explained: If we reverse the empty list, we obtain the empty list. If we reverse the list [H|T] , we end up with the list obtained by reversing T and concatenating with [H] . To see that the recursive clause is correct, consider the list [a,b,c,d] . If we reverse the tail of … Read more
Is there a numpy method which is equivalent to the builtin pop for python lists? Popping obviously doesn’t work on numpy arrays, and I want to avoid a list conversion
You could convert it to a string instead of printing the list directly: If the elements in the list aren’t strings, you can convert them to string using either repr (if you want quotes around strings) or str (if you don’t), like so: Which gives the output:
Try this: In C#, arrays have a Length property, anything implementing IList<T> (including List<T>) will have a Count property.
