How to get a python list that is converted to a string, assigned to attributes in a struct in C++

Question

Okay I am editing my original post. Apologies for not being clear enough earlier. I am relatively new to the developer role, specifically C,C++,Python and Embedded Linux.

There is a python list plist = [2,434]

This data is sent to another program written in C++ using socket programming.

plist = str(plist)
sock = socket.socket(socket.AF_INET, socket.SOCK_STRREAM)
sock.connect(('localhost',12345))
sock.send(plist.encode('utf-8'))
sock.close()

Now this data is received by the C++ program as a string. I just made a sample string as follows to give you an idea what I am getting at the C++ end.

const char* construct= "[2,434]";

Now I am trying to assign the two numbers, 2 and 434, to playerType and playerID respectively, which are part of the following structure called PLAYER_HEADER.

typedef enum
{
    START,
    STOP,
    PAUSE,
    RECORD
}PLAYER_TYPE;

typedef struct
{
    PLAYER_TYPE playerType;
    unsigned long playerID;
}PLAYER_HEADER;

So far I've tried this approach, where I am typecasting the string to a struct type.

        PLAYER_HEADER* p= (PLAYER_HEADER* ) construct;
        player = p->playerType;
        cout<<(char)player<<endl;

But this prints only '[' which is the first character of [2,434]

I would like to know why this is happening. Is there a way I can get the rest of the data?

I get that I have typecasted as a character. My end goal is to assign the two numbers to playerType and playerID .

Is there any other way I can do this? Or is there a concept in C++ I need too understand to solve this problem?
