• Desktop and GUI Applications: Python provides the Tkinter library, which can be used to develop user
interfaces for desktop applications.
• Database Access: Python provides database access by supporting different varieties of databases like MySQL,
GadFly, mSQL, PostgreSQL, Microsoft SQL Server 2000 etc.
• Business Applications: Python provides business Applications for e-commerce, ERP etc. due its highly scalable,
extensible and easily readable feature.
• Scientific and Numeric Calculation: SciPy, Pandas, NumPy are some of the built-in packages in Python which
are used for scientific and numeric calculations.
• Game Development and 3D Graphics: PySoy (a 3D game engine that supports Python 3) and PyGame are
two Python-based libraries used widely for game development. Many popular games like Battlefield 2, Frets
on Fire, World of Tanks, Disney’s Toontown Online etc. are designed using Python game libraries.
• Software Development: Python is used for general-purpose software development. It also supports audio and
video files that help in designing multimedia applications.
Recap of Python Basics
Python as a programming language was introduced in class 9 in detail. Let us now do a quick recap of some
important concepts and syntax necessary for writing a programs.
Python Character Set
A character set can be a set of valid characters like:
• Digits from 0 to 9.
• Alphabets in upper or lowercase from A to Z or a to z.
• Special symbols like $, %, ^, &, *, (, ), @, !, _, ~.
• Whitespaces like spacebar, tab key or enter key.
• ASCII or UNICODE Characters like emoji symbols or other symbols with unique code.
What is a Statement in Python?
Instructions written in a source code and are executed by a Python interpreter are called statements. In Python
we can write statements in 3 different ways. Let us learn about them in detail.
Simple Statements
By default, the end of a statement is done by pressing an Enter key. Each statement is written on a new line. For
example, a=5 is a simple statement where variable a is created with value 5.
[1]: a = 5
Multiline Statements
In Python, a statement that doesn't fit on one line can be extended over multiple lines. This can be done in
several ways:
• Using Parentheses (): You can break a long expression or function call across multiple lines if it is enclosed in
parentheses. Python allows this without any additional special characters.
[1]: result = (11 + 15 + 148 +
154 + 87)
