Is it possible to delete multiple elements from a list at the same time? If I want to delete elements at index 0 and 2, and try something like del somelist[0], followed by del somelist[2], the second statement will actually delete somelist[3]. I suppose I could always delete the higher numbered elements first but I'm hoping there is a b...
In Python, I can do: >>> list = ['a', 'b', 'c'] >>> ', '.join(list) 'a, b, c' Is there any easy way to do the same when I have a list of objects? >>> class Obj: ... def __str__(self): ... return 'name' ... >>> list = [Obj(), Obj(), Obj()] >>> ', '.join(list) Traceback (most recent call last): File "<stdin>", line 1, in ...

I get the feeling this is probably something I should know but I can't think of it right now. I'm trying to get a function to build a list where the name of the list is an argument given in the function; e.g. def make_hand(deck, handname): handname = [] for c in range(5): handname.append(deck.pop()) return handname ...
I'm having trouble with lists in OCaml. I've read conflicting statements saying whether or not the lists can be modified at runtime. Can the cons operator be used at runtime? Additionally, why is a doberman (see below) allowed to be in a list of chihuahuas? How would one go about adding another chihuahua onto the list (as attempted with...

I don't understand the behavior of Hibernate when mapping a bidirectional list. The SQL statements that Hibernate produces seem not optimal to me. Can somebody enlighten me? The scenario is the following: I have a one-to-many parent-child relationship. I map this relationship with a bidirectional list. According to the Hibernate Annota...

This might be quite a strange question since usually people bind to gridview only complex types. But I need to bind a List of Int (the same is for strings). Usually, as property to bind one uses the name of the property of the object, but when using a Int or a String, the value is exactly the object itself, not a property. Any idea of w...

I have a list of objects and I would like to access the objects in a random order continuously. I was wondering if there was a way of ensuring that the random value were not always similar. Example. My list is a list of Queues, and I am trying to interleave the values to produce a real-world scenario for testing. I don't particularly...

Each fixture contains a home and away team and a home and away score. I want to get all the teams that drew. I want to use something like IEnumerable<Team> dre...
<edit> Thanks to everyone who has answered so far. The zip and os.path.join are really helpful.

Sorry for the waffly title - if I could come up with a concise title, I wouldn't have to ask the question. Suppose I have an immutable list type. It has an operation Foo(x) which returns a new immutable list with the specified argument as an extra element at the end. So to build up a list of strings with values "Hello", "immutable", "wo...
