Convert string to float problem

[vasik006]

Hi, I have a problem converting a string to a float. The program receives data from Arduino via the serial port and processes it. But I'm getting this error message. Is there a solution? Thank you!

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

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


while True:
    arduinoData = ser.readline().decode('ascii')
    print(arduinoData)
    data = (float(arduinoData))
    mouse.position = (data, 100)
