My first thought was to start with the dictionary, something like
for key in A:
A[key] = [val for val in A[key] if val not in B]

Do you care about the order of the elements in A's value

Hello All,
I would to ask you if somebody has experience or can give direction in a

I have a meta language description (in xml) from which I should generate
code on different
languages. In my case, lisp and tcl.
Any idea in term of design, examples, links will be appreci

Hello,
I would like to get advice on the best practice to count elements in a
list (built from scractch).
The number of elements is in the range 1e3 and 1e6.
1) I could create a generator and set a counter (i +=1) in the loop.
2) or simply len(mylist).
I don't need the content of the list,

Well, I suspect you're more interested in knowing the total count of how
many as opposed to counting how many. To get the total count of how
many use len(mylist).

The nice thing about Python is you don't have to build things from scratch,
and I imagine most people would discourage on account of it being a waste of
time, other then education value.
But the "best practice" in my humble opinion would be to use the built in
