Object-Oriented: Python supports object-oriented programming concepts of classes and
objects. The programs are built around objects that combine both data and functionality.
Interpreted: The Python interpreter executes the code one line at a time. Internally, Python
converts the source program into an intermediate form called bytecode and then translates
this to run on the specific platform.
Interactive mode: Python IDLE (Integrated Development and Learning Environment)
comprises of Python shell and Python Editor. Python shell is an interactive interpreter window,
where Python code is typed at >>> prompt and run and the shell responds with the result.
Cross-platform: A Python program can run on any platform without making changes to it
which means that the same program will run on Windows, Linux, Macintosh, etc.
Python is a general-purpose, dynamic, interpreted, interactive, high-level, multi-platform and
object-oriented programming language.
HOW TO USE PYTHON IDLE
Step 1 Click on Start → All programs → Python 3.7 → IDLE (Python 3.7 32-bit)
Step 2 This will open the main IDLE window (also known as Interpreter or shell window).
Step 3 The IDLE window has two parts: Menu bar and Prompt (>>>)
Menu bar
Prompt
Python IDLE Window (Prompt)
My First Python Program
Python prompt allows you to enter commands directly and get the output instantly by pressing
the Enter key.
To write a program, perform the following steps:
Step 1 Write the following print statement at the prompt
>>> print ("Hello World.")
Step 2 Press the Enter key.
