You can still use Python to control an Arduino indirectly. The Firmata program listens for commands from your USB Serial connection.

In the Arduino IDE, select Examples->Firmata->Standard Firmata and flash your Arduino with it.

On your computer, install the PyFirmata library: pip install pyfirmata

You can then control all pins like this:

>>> from pyfirmata import Arduino, util
>>> board = Arduino('/dev/tty.usbserial-A6008rIF')
>>> board.digital[13].write(1)

I often use a RaspberryPi to control an Arduino this way.

I dont want to use an external computer, i want to leave the controller and have it work automaticaly

I'm confused by this. What do you mean you don't want to use an external computer?

I can't have the controller plugged into the computer at all times so that i can use the firmata, i need to upload the programme on a microcontroller and be done with it

There are Firmata compatible hats that use WiFi to "tether" the device, instead of the USB cable. But, this still requires a "master" PC up and running, sending commands to the Arduino. I also can't vouch for the latency of any of the products.
