How to Set Your Screen Brightness to Black in Python?

Estimated read time 1 min read

It’s not possible to set your screen brightness to black using Python or any other programming language. Black is not a brightness level; it’s a color. Brightness is a measure of the amount of light emitted by the display, typically measured in units like nits or candelas per square meter (cd/m²).

While it’s possible to turn off the backlight of an LCD display to make the screen appear black, this would not be a useful or practical thing to do in most cases.

If you want to dim the screen or adjust the brightness in Python, you can use a library like pybrightness or brightness to interact with the operating system’s display settings. Here’s an example code that demonstrates how to set the brightness to 50% using the pybrightness library:

import pybrightness

# Set brightness to 50%
pybrightness.set_brightness(0.5)

Note that the pybrightness library only works on certain operating systems, such as Windows and Linux. The brightness library, on the other hand, is designed for macOS.
