This package installs the avrdude (x32 and x64-only) binaries for Windows via pypi/pip. There is a single python function in this library which allows you to get the path of the avrdude executable:
from avrdude_windows import get_avrdude_path
print(get_avrdude_path())
The MIT license in this repository only applies to the single python function mentioned above - avrdude is licensed separately. Source code and binary releases for avrdude can be found in the project repository.
If you are using Mac, you should use Homebrew instead:
brew install avrdude
Or on Linux, you should use the package manager of your distribution, for example:
sudo apt install avrdude
