推荐答案

您似乎正在尝试通过运行命令python来启动Python解释器.

It looks like you are trying to start the Python interpreter by running the command python.

但是解释器已经启动.它将python解释为变量的名称，但未定义该名称.

However the interpreter is already started. It is interpreting python as a name of a variable, and that name is not defined.

请改用此方法，您应该希望看到Python的安装按预期运行:

Try this instead and you should hopefully see that your Python installation is working as expected:

print("Hello world!")
