function IsAOrB(const p_Id: string): boolean;
begin
  if ((p_Id = 'A') or (p_Id = 'B')) then begin
    Result := true;
    Exit;
  end;
  Result := false;
end;

Result := ((p_Id = 'A') or (p_Id = 'B'));

That would have been enough. But this also features Exit and an asymmetrical if.

product = None
for key in dictionary.keys():

	else:
		product = itertools.product(product, dictionary[key])

product = "{0}".format(list(product))
product = re.sub(r"\), \(+", "], [", product)
product = re.sub(r"\(+", "[", product)
product = product.replace(")]", "]]").replace(")", "")
product = ast.literal_eval(product)

Ok, I have a weird array of objects as output of itertools and I need an array of strings... 1 - Convert the array to string 2 - Clean it up with regex and replace 3 - Convert the string to array 4 - Problem solved

socket.in wasn't behaving as advertised (broadcasting to all rooms). I decided to take matters into my own hands.
