Introduction of ‘Tuple’ in .NET Framework 4.0, really filled in a missing piece in C#. Apart from giving us the ability to interoperate with functional languages like F# or Python/Ruby, It does offer the conv
3.Dict系列 Python遍历相关: #每一次相当于取一个元组,那可以用之前讲的例子来简化了:c,d=a #等价于:c=a[0] d=a[1] fork,vin infos_dict.items():print("Key:%s,Value:%s"%(k,v)) NetCore:方式和Python差不多foreach (KeyValuePair<string, object> kvin infos_dict){Console.WriteLine($"Key:...
tuple是C++ 11新引进的build-in structure,但其实在其他语言中tuple的使用已经行之有年(e.g. Javascript和Python中都有tuple)。C++ 11中tuple的引进是为了降低不同programming languages之间的隔阂,比方说有些programmer于本是写Python的,他在Python的世界中用tuple已经很习惯了,但是当他今天转行来写C++时,如果原本在...
>>> int <class 'int'> >>> len <built-in function len> >>> def func(): ... pass ... >>> func <function func at 0x1053abec0> >>> import math >>> math <module 'math' from '.../math.cpython-312-darwin.so'> >>> [int, len, func, math] [ <class 'int'>, <built...

One of the most common use cases of tuples is as a method return type. That is, instead of definingoutmethod parameters, you can group method results in a tuple return type, as the following example shows: C# int[] xs =newint[] {4,7,9};varlimits = FindMinMax(xs); Console.WriteLi...
IComparable.CompareToCompares the current Tuple<T1, T2, T3, T4> object to a specified object and returns an integer that indicates whether the current object is before, after, or in the same position as the specified object in the sort order. ...
