Errors with Code

[RobinPun]

Hello,

I was trying to use your code to gain some graphs with the distance detection performed. However the code seems to have some errors when I run it. For instance after configuring the TF-Luna Lidar camera with my Pi, I tried to run the tfluna_test code whivh gave me this:
Python 3.9.2 (/usr/bin/python3)

%Run tfluna_test.py
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 322, in open
self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK)
PermissionError: [Errno 13] Permission denied: '/dev/serial0'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/home/pi/Desktop/tfluna-python-main/tfluna_test.py", line 19, in
ser = serial.Serial("/dev/serial0", 115200,timeout=0) # mini UART serial device
File "/usr/lib/python3/dist-packages/serial/serialutil.py", line 244, in init
self.open()
File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 325, in open
raise SerialException(msg.errno, "could not open port {}: {}".format(self._port, msg))
serial.serialutil.SerialException: [Errno 13] could not open port /dev/serial0: [Errno 13] Permission denied: '/dev/serial0'

Please may I receive a solution to this error code promptly,

Thank you very much,
Robin

It's not a python issue.
Probably, you have to disable serial console in raspi-config.
