The tuple in c++11 is an n-ary variable tuple, which is equivalent to a struct with n elements, except that the members of the struct are anonymous, and a Get () method is provided in the tuple to get the value of the element corresponding to the subscript. You can also construct a tuple object by using the Make_tuple

Tuple is a data type that can be aggregated and managed with more than 2 data. It would be nice if C # were there. The tuple instance code for F # is as follows: #light let　data　=　(1,2) printfn　"%A"　data printfn　"%A"　(fst　data) printfn　"%A"　(snd　data) FST, SND, respectively, represent first, Second, which can be used to take out the original two elements. The results of the operation are: (1,　2) 1 2 (1

The tuple is a new feature introduced by C # 4.0. You need to base the. NET Framework 4.0 or later. A tuple uses generics to simplify the definition of a class. The tuple is used more forThe return value of the method, if a function returns more than one type, so it is not used for output parameters such as Out\ref, you can define a

The knowledge of the list is actually similar to the array in C, which can be inserted and modified. LIST=[A,B,C,D]Tuple tuples, once initialized, cannot be modified. Benefits and absolute safety.Define an empty tuple: t= ()Define a tuple with only one element: t= (1,), Python will recognize this element by adding a comma after the parenthesis element, or Python

Python has three built-in functions: Lists, tuples, and strings, which convert each other using three functions, str (), tuple (), and List (), as shown below: >>> s = "xxxxx">>> List (s)[' x ', ' x ', ' x ', ' x ', ' X ']>>> tuple (s)(' x ', ' x ', ' x ', ' x ', ' X ')>>> Tuple (list (s))(' x ', ' x ', ' x ', ' x ', ' X ')>>> list (

When I do the selenium element object stripping today (I put the element object into a variable of the tuple type, format: User = ("id", "x-auto-2")), encounter a tuple variable, and the STR string variable as a parameter to pass the value of the problem, found that the output of the string is the first value in the tuple, the study of the majority of days, and f

The action and Func generic delegates are actually a. NET framework predefined delegate, which is an attribute introduced by 3.5. Basically covers all commonly used delegates, so it is generally not necessary to re-declare them.The action series generic delegate, which is a delegate with no parameters returned, can have up to 16 arguments or no arguments; the Func series delegate is a delegate with a return value and can have up to 16 parameters;Tuples are a new feature introduced in C # 4.0, wh

In Python, the sequence types are str, bytes, ByteArray, list, tuple, range. The so-called sequence, the description is orderly, you can do some specific operations through the index. First understand the two most important of the sequence objects: STR and list, and then explore the common operation of the next sequence object.String: strText data in Python is handled by a Str object or string. A string is an immutable sequence of Unicode encodings (s
