我是mac 使用homebrew 安装的python 3.9，提示如下，请问我有安装成功吗？

==> python@3.9
Python has been installed as
/usr/local/bin/python3

Unversioned symlinks python, python-config, pip etc. pointing to
python3, python3-config, pip3 etc., respectively, have been installed into
/usr/local/opt/python@3.9/libexec/bin

You can install Python packages with
pip3 install
They will install into the site-package directory
/usr/local/lib/python3.9/site-packages

tkinter is no longer included with this formula, but it is available separately:
brew install python-tk@3.9
