मैंने पढ़ा है कि कैसे अजगर ऑब्जेक्ट बनाता है और उन लोगों के लिए "टैग" डालता है जो उस आवंटित चर के रूप में होते हैं। हालांकि, मुझे लगता है कि अगर दो स्ट्रिंग या पूर्णांक समान मूल्यों के साथ हैं, तो यह केवल एक मेमोरी स्थान को आवंटित करता है, सूचियों, ट्यूपल्स, डीआईसीएस के विपरीत। क्या कोई नियम या प्रकार की सूची होती है जब एक मामला होता है लेकिन दूसरा नहीं? विशेष रूप से, अगर मैं 

 > gt; & gt; & gt; एक्स, वाई = 'ए', 'ए' & gt; & gt; & gt; एक्स है y सत्य है & gt; & gt; X, y = 1,1> gt; & gt; & gt; एक्स सच है

लेकिन दूसरी ओर, अगर मैं करता हूं 

 > gt; & gt; X, y = {'a': 1}, {'a': 1}> & gt; & gt; X है y झूठी और gt; & gt; & gt; X, y = (1,), (1,) & gt; & gt; & gt; X है y झूठी और gt; & gt; & gt; X, y = [1], [1]> gt; & gt; & gt; पायथन में स्ट्रिंग्स अपरिवर्तनीय हैं और पुन: उपयोग किए जा रहे हैं। X, y

I need to convert a QByteArray into a structure. I have such a structure: struct mavlink_attitude_t {/// & lt; Summary & gt; Timestamp (millisecond from system boot) & lt; / Summary & gt; Quint 32 Time_boot_ms; /// & lt; Summary & gt; Roll angle (rad, -pi .. + pi) & lt; / Summary & gt; Float roll; /// & lt; Summary & gt; Pitch angle (red, -p + + pi) & lt; / Summary & gt; Boat pitch; /// & lt; Summary & gt; Angle of O (Red, -P. + Pi) & lt; / Summary & gt; Float yao; /// & lt; Summary & gt; Angular Speed ​​Roll (Rod / S) & lt; / Summary & gt; Float rollspeed; /// & lt; Summary & gt; Pitch angular momentum (rad / s) & lt; / Summary & gt; Float pitchspid; /// & lt; Summary & gt; Yoga's angular momentum (RD / S) & lt; / Summary & gt; Float Yspeed; }; And I come from a Quetbeat Serial Port. I was already using the union but I think it can not be used for QByteArray, i...

c# - How to know the number of Threads created and limit the Tasks accordingly -

-
It is very clear that with task as async / await Instead of calling the asynchronous call threads , my question is: Is there a way to monitor threads while completing these tasks? This is because I can decide an optimal number of times for the thread that the thread does not eat too many CPU cycles at the same time (the CPU is intensive to handle the work). We take an example below (output is also mentioned) Although the program is completed in 5 seconds, but it has two threads (id = 1,4 ) if I increase the number of 6 instead of 2, then it creates 4 threads I know that this is the CLR thread OS thread (which is 4 in my machine Are), but I would like to know how they are mapped O (with actions) and use the same CPU. Is there any way to get it? Test code Fixed zero main (string [] args) {RunTasksWithDelays (). ); } Static async Task Run Task with Dislay () {Stopwatch S = Stopwatch. Startup (); Console.light line ("thread id =" + thread.content.trade.manag...
