No Python 3.3, há uma nova opção para adicionar automaticamente o Python a% variável de ambientePATH
.
Besides using the automatically created start menu entry for the Python interpreter, you might want to start Python in the command prompt. As of Python 3.3, the installer has an option to set that up for you.
At the “Customize Python 3.3” screen, an option called “Add python.exe to search path” can be enabled to have the installer place your installation into the %PATH%. This allows you to type python to run the interpreter. Thus, you can also execute your scripts with command line options, see Command line documentation.
No entanto, o instalador do Python no Windows, por padrão, associa arquivos Python ao interpretador Python, para que os usuários possam executar scripts Python apenas clicando no script Python ou em um link para ele.
