python - Convert string into hex to send for serial communication -

-

i have string numbers 5:240. have send numbers string hex representation. number must in range of 2 bytes. but, want send exact representation on serial port '\x00\x05\x00\xf0'. can me out on this?

i have tried following snippets no success:

b='5:240' b = b.split(':') in range(len(b)):     print hex(int(b[i]))     print len(hex(int(b[i])))

result:

0x5 3 0xf0 4

output shows hex conversion not possible me send on serial port, cause length varying. can resolve issue?

you can use hexadecimal format specifier, x:

def word_hex(w):     = int(w / 256)     b = w % 256     return "{0:#0{1}x}{2:#0{3}x}".format(a,4,b,4).replace("0x", "\\x")  b='5:240' b = b.split(':') in b:     print(word_hex(int(i)))

prints

\x00\x05 \x00\xf0

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
