2. Python is a widely used general-purpose, high
level programming language. It was initially
designed by Guido van Rossum in 1991 and
developed by Python Software Foundation. It
was mainly developed for emphasis on code
readability, and its syntax allows programmers
to express concepts in fewer lines of code.
Python is a programming language that lets
you work quickly and integrate systems more
efficiently.
There are two major Python versions- Python 2
and Python 3. Both are quite different.

3. • Beginning of the Python Language:
• Before starting python language we need an interpreter to interpret and run the program.
• Linux is the best interpreter for python language as it comes bundled with the python
language.
• Example with a program:
• # Script Begins
•
• print(“PAKISTAN")
•
• # Scripts Ends
• Let us analyze the script line by line.
• Line 1 : [# Script Begins] In Python language comments begin with #.
• Line 2 : [print(“PAKISTAN”)] In a Python script to print something on the console print()
function is used – it simply prints out a line. And its also includes a new line.
• Line 3 : [# Script Ends] This is just another comment like Line 1.

4. *Features of Python Language:
* 1) Easy to Learn and Use
* Python is easy to learn and use. It is developer-friendly and high level programming language.
* 2) Expressive Language
* Python language is more expressive means that it is more understandable and readable.
* 3) Interpreted Language
* Python is an interpreted language i.e. interpreter executes the code line by line at a time. This makes
debugging easy and thus suitable for beginners.
* 4) Cross-platform Language
* Python can run equally on different platforms such as Windows, Linux, Unix and Macintosh etc. So, we can
say that Python is a portable language.
* 5) Large Standard Library
* Python has a large and broad library and provides rich set of module and functions for rapid application
development.
* 6) GUI Programming Support
* Graphical user interfaces can be developed using Python.
* 7) Integrated
* It can be easily integrated with languages like C, C++, JAVA etc.
* 8) Extensible
* It implies that other languages such as C/C++ can be used to compile the code and thus it can be used further
in our python code.

5. Python language elements
*Basic data types and containers
* Python has several basic data types and containers. Becoming familiar with them is essential to
effective use of Python, and is a good starting point for learning Python.
*Variable names and assignment
* Python variable names are case-sensitive and start with a letter or an underscore. A leading
underscore may be used by convention to indicate a variable
*Functions
* When programs get too complex, they are likely to be full of bugs and hard to maintain. The most
fundamental construct for keeping complexity under control is the function.
*Exceptions and tracebacks
* Exceptions are part of a program flow control mechanism that is specially designed for handling
errors or other “exceptional conditions”, but that can be used more generally. A traceback is the error
report from an uncaught exception, showing the chain of function calls leading to the exception.

8. Microsoft Excel interface
Excel interface is very simple and efficient. It provides methods for carrying out tasks with minimum clicks of the
mouse. It provides the ways to work with the keyboard.
Elements of excel interface
Worksheet:
Worksheet is where you enter all your data.
Worksheet is made up of rows and columns.
Rows are labeled with numbers and columns are labeled with letters.
Workbook:
Workbook is a group of worksheets saved together as one excel file.
Each workbook in excel contains 3 worksheets. The first sheet is called sheet 1 and so on.. .
Active cell:
Active cell is used to tell excel where you want to enter or edit data.
Title bar:
It is located at the very top of the screen .
It displays the name of the current work book on it.
Menu bar:
Menus vary program to program.
Menu commands are used to moving, saving, erasing, printing, saving, and changing the appearence of data etc.
Toolbars:
Toolbars provide shortcuts to. Menu commands.
Toolbars are located just below the menu bar.
It consist of icons that act as shortcuts to the commands.
Toolbar that appears below menu bar is called standard toolbar.

9. *Formula bar:
* This bar displays the location of the active cell and the value or formula used in the active cell.
*Cell:
Intersection of row and column is call cell.
Cell holds data.
Cell may contain text, numbers, and even graphical patterns.
* Cell Address:
Cells are identified by combination of their column letter and row number.
* Sheet Tabs:
Sheet tabs at the bottom of the workbook.
Sheet tabs are used to move from one sheet to another in a workbook.
* Status bar:
It appears at the bottom of excel interface.
It displays information about a command, a toolbar icon or an operation in programs
Smart tags:
* Smart tags appears when the user makes an entry and Microsoft excel believes the user may want to
change.
* Smart tags provide the facility to make changes easily.

*About Windows XP
* Windows XP is developed by Microsoft.
* It was released in 2001.
* XP stands for experience.
* Easier to use
* Available in different versions such as XP Home, XP Professional, and XP Media Centre.
* Windows XP Professional is often used in business environment and by home.
* The media Centre is built on XP Professional.
*Features of Windows XP
*New user interface:
* Provides a new user interface with different visual style. Desktop and taskbar are more attractive
and easier to use. Windows layout and design of start menu is also changed.
*Easier to use:
*Provides an easier way to work with files and folders. It saves all files in My
Documents folder on desktop by default. It also manage a recently used files
for quick access later.
* Easier to manage
* Multitasking

13. *Multi-User:
* It means that many users can use the computer at a same time. These users can be connected to a computer
over the internet.
*Clean Desktop Wizard:
* By default, the desktop cleanup Wizards runs every sixty days. It cleans-up desktop by moving unused
desktop shortcuts to a folder called unused desktop shortcuts.
*Networking:

*Multiprocessing:
* Multiprocessing is the capability to support and utilize multiple processors in a computer. Two or more
processors can execute different programs at the same time . It increase the output of the computer.
*System restore:
* It is used to restore operating system in case of any problem. The operating system is restored to a previous
state without any loss of data.
*Latest Hardware Support:
* Includes the latest drivers to support latest advancements in computer hardware technology.
*Task panel:
* It provides an easy way to access the most commonly used folder tasks. The task panel displays a list of
hyperlink task to the left of the folder contents. For example, My pictures and My music folders provide
links to manage pictures and music files.
