在Powershell Prompt中，我根据安装说明输入了以下内容。
& $([scriptblock]::Create((New-Object Net.WebClient).DownloadString('https://platform.activestate.com/dl/cli/AS700/install-latest.ps1'))) -c'state activate --default wmooreavista/Python-3.9.9-Windows'命令的输出。

然后我关闭了窗口，以为Python 3.9已经安装了，但当我搜索我的硬盘时，我找不到目录 "C:\python3"，也找不到可执行文件 "python3.exe" ...什么原因？ 还有，为什么用Powershell命令行安装完Python后，会启动一个cmd.exe外壳？ 这真是令人困惑......在用Powershell命令安装完python3并关闭安装命令行窗口后，如何启动python3？
