Convert string to float problem

[vasik006]

Oh, thank you. It works perfectly with try/except! Also I have one more question. I need to make value bigger (multiply), but this does not work. How can I do it?

from pynput.mouse import Button, Controller
import time
import serial

mouse = Controller()
ser = serial.Serial('COM3', baudrate=9600, timeout=1)


while True:
    try:
        arduinoData = ser.readline().decode('ascii')
        data = (arduinoData)/5
        print(data)
        mouse.position = (data, 100)
    except:
        print("fail")
        break

EDIT: Solved also this.
