Sending 8 bit int through Serial

[achen225]

Hi, I'm trying to print an 8 bit integer from my microcontroller and receive it through my com port in python. However, when I write something like this

uint8_t val = 25;
Serial.print(val);

and read through my python code, I found that the microcontroller sends this value as 2 bytes (one 2 and one 5) rather than the 8bit value of 25. Is there a way to send this as the 1byte value and not 2 bytes?

Serial.write(val);
