You started a topic in the Uncategorised category of the forum whose description is

Your topic has been moved to the Programming category
What system is Python running on ? A PC, perhaps ?
Which Arduino board do you have ?
Python3 and arduino nano.
Laptop(python3)
Who is the transmitter?
Who is the receiver?
Which communication protocol is used?
Which transport medium is used?
The question I´ve forgoten?
You need a Bluetooth adapter, such as the HC05, connected to the Nano. You use SoftwareSerial to create a serial port on 2 pins other than 0 and 1 and connect the HC05 to them
In the sketch, when data is available on the SoftwareSerial port you process it
See PC - Arduino comms using Python -- updated - Interfacing w/ Software on the Computer - Arduino Forum for some ideas
NOTE : in the Python code, open the serial connection once and only once because each time you open it the Nano will reset

Hello aliarad777
This is a nice project to get started.
Keep it simple and stupid firstly.
Follow the example code that comes with the library or
run some tutorials for the hardware selected.
If you are happy with the results of the tutorials you can merge these to your project.
Have a nice day and enjoy coding in C++.
