i have list of tuples this: x = [('y', [1, 2]), ('y', [3, 4]), ('y', [5, 6])] and want return me this: [(1, 2), (3, 4), (5, 6)] note: tuple number can vary, may also: x = [('y', [1, 2, 3, 4]), ('y', [5, 6, 7, 8]), ('y', [9, 10, 11, 12]), ('y', [13, 14, 15, 16])] which produce [(1, 2, 3, 4), (5, 6, 7, 8), (9, 10, 11, 12), (13, 14, 15, 16)] use list comprehension second item of each element: new_list = [tuple(b) a, b in old_list]

i have following issue related reflection , have method looks : [testmethod()] public void steamaccess() { testread = new testread(); steammap = new steammap(); // preparing parameters of csv actions a.writemessageparams.uiitemedittext = testcontext.datarow["searchquery"].tostring(); //read , execute testmethod testread.read(a, testcontext); } this codeduitest , steammap class ( uitest map ). writemessageparams class, real method writemessage class allows me override string gets used tests writemessage method, , plan make part of code more dynamically in read method. : a.writemessageparams.uiitemedittext = testcontext.datarow["searchquery"].tostring(); my problem happens in testread.read context follows : when method running have access actions respective instance ( a in case ) , if supposed have use a.writemessageparams.uiitemedittext context know it,

i have 2 classes class , class b both of them template classes member function in want act in special way when type of b , in normal way other types don't know how ? template <class b> class b { private: t m; public: ...... member functions } template <class t> class { private: t var; public: void dosomething(); }; template <class t> void a<t>::dosomething(){...........//implementation} template <class t> void a<b<t>>::dosomething(){................//different implementation} you can specialize a way: template <class t> class a<b<t>> { // ... }; this instance of partial template specialization . if refuse specialize entire class, can defer work a<t>::dosomething() function dosomethingfora<t>(a &) partially specialized, , possibly friend of a<t> .
