Original Book Contents
23.5.2 Gettting Started
The best way to learn Python for the first time is through Python IDLE. Python IDLE can be used in window or terminal environments.
23.5.2.1 Starting in the Desktop GUI environment
You can start Python using the desktop or Applications Menu.
Menu [Python 2] allows you to use the integrated development environment for Python version 2. If you choose menu [Python 3], you can use the integrated development environment for Python version 3.
When the program starts, the following Python Shell screen appears, which is a work screen for creating and running the program.
Figure 23‑7 Python Shell screen
However, it is inconvenient to develop a large number of programs because the shell is supposed to input commands one line at a time, and it executes immediately after inputting. So, if you select menu File à New Window, a new empty screen is opened, and there, you can execute a large number of programs in bulk or save the whole contents as a file and use it again later.

23.5.2.2 Working in Terminal Environment
