I faced same problem with Python 3.12 , xampp (php 7.3) then I do "pip uninstall mysql-connector-python"

then again install "pip install mysql-connector-python==8.0.21"

and now its working fine. NOTE:: directly pip install mysql-connector-python is installing about 9 version, so its not working, thats why I uninstall 9 and install 8.0.21 version.
