python 2.7 - How to build a map from two lists using zip? -


ये मेरी सूची है:

projects = ["A", "B", "सी"]

घंटे = [1,2,3]

मुझे मेरा अंतिम उत्तर होना चाहिए: {ए: 1, बी: 2, सी: 3}

क्या कोई सुझाव है?

कोड टुकड़ा कोड (ज़िप) (प्रोजेक्ट्स, घंटो) ट्यूपल्स (कुंजी, मान) की एक सूची तैयार करेगा, जिसका उपयोग मैप फ़ीड करने के लिए किया जाएगा (आमतौर पर अजगर में शब्दकोश कहा जाता है) निर्माता: Dict

c - Performance of System() -

After the function in C, for the system (), it affects the hardware counters, so how do you order that The example displayed for the example you are trying to view lets the IM use the display API (PAPI) and the program is a precompiled matrix multiplication application. PAPI_start_counters (); System ("./matmul"); PAPI_read_counters (); // Print the values ​​PAPI_stop_counters (); I'm clearly missing a bit, but I'm trying to figure out what it is possible to say, counter receiving a program im running Is through use. With my tests I will get wild numbers like below, they are clearly wrong, just want to find out why total bicycle =========== 140733358872510 instructions complete =========== 4203968 Floating Point Instructions =========== Floating Point Operations =========== 4,196,867 Weight ======= ==== 140733358872804 store ======= ==== 4204037 branches taken =========== 15774436 System () Normally it is a very slow function, on Linux, it is ...

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title').

c++ - How to define methods in a base class that only work in derived classes? -

The title is slightly ambiguous, so I will say an example of what I want to achieve: Class ValuePtr {Public: Operator Canned void * () {return glm :: value_ptr (* this); // value ptr will not work on this class // (works only on glm type)}}; Square mat4x4: public glm :: mat4x4, public valuePtr {// ... but will work here}; Square Vec3: Public glm :: vec3, Public ValuePtr {// ... and here. } Is such a thing possible? glm :: value_ptr works only on glm type like glm :: mat4x4 , glm: : Vec3 , etc. The above seen method works if I implement it directly into derivative classes, but they should all be defined as operator construct * zero * in the same way. I should behave like a special behavior: define it in the general base class, whereas definition only works in derived classes. Thank you for the answer, I use this solution: template & lt; Class T & gt; Class ValuePtr: Public T {Public: Operator Constant * () {return glm :: value_ptr (* this); }}; Class ...
