pyserial/serial "has no attribute 'Serial' "

[gowb0w]

Hi there ! glad to discover this forum.

first, i am a beginner, i want to learn Python etc.

i was typing this program :

import serial 
serial_port = serial.Serial(port = "COM3", baudrate = 9600)
serial_port.readline()

and i get this error code :

Error:
File "c:\Users\Mérill\Desktop\pytharduino2\ardseri.py3", line 2, in <module>
    serial_port = serial.Serial(port = "COM3", baudrate = 9600)
                  ^^^^^^^^^^^^^
AttributeError: module 'serial' has no attribute 'Serial'

i tried to reinstall the pyserial library, uninstall the serial library,

i tried the method

from serial import Serial

it does not help. i have an other error code

Error:
File "c:\Users\Mérill\Desktop\pytharduino2\ardseri.py3", line 1, in <module>
    from serial import Serial 
    ^^^^^^^^^^^^^^^^^^^^^^^^^
ImportError: cannot import name 'Serial' from 'serial' (unknown location)

so i tried a lot of different common solutions to fix this problem. But i am stuck

i am using Python3.x
