Python Interpreter or Shell
The Python Interpreter or Shell is present below the Menu Bar. It contains the Python command prompt
>>>. Commands are typed at the prompt, and their results are displayed below the commands.
Status Bar
The Status Bar is present at the bottom of the IDLE window. It displays the line number and column
number at which the cursor is in the Interpreter.
PYTHON WORKING MODES
Python provides two modes of working in the IDLE. Let us learn about them.
1. Interactive Mode or Shell Mode: In the Interactive mode, each command is typed at the prompt.
When we press the Enter key, the Interpreter executes the command and displays the result below the
command. In the interactive mode, one command can be typed at a time. The commands are not saved,
and hence, cannot be reused. The Interactive mode can display text messages, results of calculations,
and values of variables.
To use the Interactive mode, type a command at the prompt
and press the Enter key.
For example, type the following commands one by one at
the prompt and press the Enter key after each command:
• print(“Welcome to Python”)
• 30 + 20
The Interactive mode is a great way to learn Python
commands and debug small code snippets.
2. Script Mode: The Script mode, also known as Batch
Processing mode, lets you execute several Python commands
together in a sequence. This is done by saving the set of
commands as a file called a script or program. The saved
script can be reused later as required. Once the script is
created, you can execute the script to view the output.
WORKING IN SCRIPT MODE
Most of your programming will be done in the Script mode. The Script mode lets you create, save, open,
execute, and close scripts. Time Saver
To create a new script:
1. On the Menu bar, click the File menu. New script: Ctrl + N
The File menu opens.
1 2. Select the New File option.
2 3 The untitled Editor window opens.
3. Type the required Python
commands in the scripts area.
