Python IDLE : Interactive Mode
Let us assume that we've already installed Python (here we installed Python 3.2 on a standard pc with windows 7 OS). Click on start button and find Python 3.2 tab in installed programs.
Now clicking on Python 3.2 tab you can see the Python program development tool named IDLE (Python GUI).
To start IDLE click on IDLE (Python GUI) icon, you will see a new window opens up and the cursor is waiting beside '>>>' sign which is called command prompt.
This mode is called interactive mode as you can interact with IDLE directly, you type something (single unit in a programming language) and press enter key Python will execute it, but you can not execute your entire program here. At the command prompt type copyright and press enter key Python executes the copyright information.
Now Python is ready to read new command. Let's execute the following commands one by one.
