A tuple is a good way to pack multiple values into that cookie without having to define a separate class to contain them. I try to be judicious about this particular use, though.
3 A tuple is an immutable list. This means that, once you create a tuple, it cannot be modified. Read more about tuples and other sequential data types here.
Note: This is asking for the reverse of the usual tuple-to-array conversion. I have to pass an argument to a (wrapped c++) function as a nested tuple. For example, the following works X = MyFunc...
Using a tuple instead of a list is like having an implied assert statement that this data is constant, and that special thought (and a specific function) is required to override that. Some tuples can be used as dictionary keys (specifically, tuples that contain immutable values like strings, numbers, and other tuples).
Named tuples are basically easy-to-create, lightweight object types. Named tuple instances can be referenced using object-like variable dereferencing or the standard tuple syntax. They can be used similarly to struct or other common record types, except that they are immutable. They were added in Python 2.6 and Python 3.0, although there is a recipe for implementation in Python 2.4. For ...
However, assuming the OP requires a tuple for output, the difference comes in the conversion back. For proof: take tuple () off the generator and they'll both return instantly, but tuple () the filter and it takes longer proportional to the size of tupleX.
new Tuple<int,int>(1,2); Tuple.Create(1,2); Is there any difference between these two methods of Tuple creation? From my reading it seems to be more a convenient shorthand than anything like object creation in C++ (heap vs stack).
Have you assigned the name 'tuple' as a variable name? it should work fine. L is a list and we want to convert it to a tuple. L = [1, 2, 3] tuple (L) By invoking tuple, you convert the list (L) into a tuple. As done above. >> (1, 2, 3) you can go ahead and access any item in the tuple using the square brackets. L [0] 1
This is a follow-up to my previous question on pretty-printing STL containers, for which we managed to develop a very elegant and fully general solution. In this next step, I would like to include ...
