Translate C++ code that uses char type to Python -


how code in python? nrcomm1->sendchar can replaced serial.write(a_char)

void prepare() {     char temp[50];     sprintf(temp,"%04xt2000a", 76);      send(temp); }  void send(char *tx_string) {     unsigned char checksum = 0x02;        nrcomm1->sendchar(0x02);     while(*tx_string)     {         nrcomm1->sendchar(*tx_string);         checksum ^= *tx_string++;     }     nrcomm1->sendchar(0x03);     checksum ^= 0x03;                                  nrcomm1->sendchar(checksum); }

it (not working example, started):

update: provided hints how make example work...

def prepare():     temp = "%04xt2000a" % 76     send(temp)   def send(tx_string):     checksum = 0x02     serial.write(checksum)      # hint: int conversion not work since tx_string     # string representation of hex value, add conversion code     while(tx_string):         serial.write(int(tx_string[0]))         checksum = checksum ** int(tx_string[0])         tx_string = tx_string[1:]      serial.write(0x03)     checksum = checksum ** 0x03     serial.write(checksum)
