The others are right that the problem is the : operator. I would say that your areTheySame function that returns a list is the wrong approach anyway, though. Rather than switch to the ++ operator, a better implementation of that function would be: As you can see, this is a pretty simple implementation. Also, consing … Read more
Use str.join:
itertools.product Available from Python 2.6. Which is the same as,
You can do this very simply using LINQ. Make sure this using is at the top of your C# file: Then use the ToList extension method. Example:
Firstly, you can’t do new List(); it is an interface. To make a list of int Arrays, do something like this : P.S. As per the comment, package for List is java.util.List and for ArrayList java.util.ArrayList
Try a list comprehension: This goes through l, multiplying each element by two. Of course, there’s more than one way to do it. If you’re into lambda functions and map, you can even do to apply the function lambda x: x * 2 to each element in l. This is equivalent to: Note that map() returns a map object, not a list, so if you … Read more
You cannot assign to a list like lst[i] = something, unless the list already is initialized with at least i+1 elements. You need to use append to add elements to the end of the list. lst.append(something). (You could use the assignment notation if you were using a dictionary). Creating an empty list: Assigning a value … Read more
You can use the LINQ Concat and ToList methods: Note that there are more efficient ways to do this – the above will basically loop through all the entries, creating a dynamically sized buffer. As you can predict the size to start with, you don’t need this dynamic sizing… so you could use: (AddRange is special-cased for ICollection<T> for efficiency.) I wouldn’t take this … Read more
c# 7.0 lets you do this: If you don’t need a List, but just an array, you can do: And if you don’t like “Item1” and “Item2”, you can do: or for an array: which lets you do: tupleList[0].Index and tupleList[0].Name Framework 4.6.2 and below You must install System.ValueTuple from the Nuget Package Manager. Framework 4.7 and above It is built … Read more
If you want to modify the list in-place,
