3. Introduction of Python
• Python is a general-purpose interpreted,
interactive, object-oriented, and high-level
programming language.
• It was created by Guido van Rossum during
1985- 1990.
• Like Perl, Python source code is also available
under the GNU General Public License (GPL).

4. Overview of python
• Python is Interpreted
• Python is Interactive
• Python is Object-Oriented
• Python is a Beginner's Language

5. Features of Python
 Easy-to-learn
 Easy-to-read
 Easy-to-maintain
 A broad standard library
 Interactive Mode
 Portable
 Extendable
 Databases
 GUI Programming
 Scalable

6. Organizations using python
• Google: server side official language
• Facebook: third most popular language at the social media
giant
• Instagram: running the world’s largest deployment of the
Django web framework, which is written entirely in Python.
• Spotify: music streaming giant is a huge proponent of
Python
• Netflix: Netflix uses Python in a very similar manner to
Spotify.
• Dropbox: cloud based storage system uses Python in its
desktop client.
• Reddit: Software backbone

7. Python applications in
various domains
• Web Development
• Game Development
• Machine Learning and Artificial Intelligence
• Data Science and Data Visualization
• Desktop GUI
• Web Scraping Applications
• Business Applications
• Audio and Video Applications
• CAD Applications
• Embedded Applications

8. Installation
• Presently the version in use is Python 3.x
• But you can also use Python 2.x ,like 2.7..etc .This
depends on your system and your interest.
•To download the Python interpreter go to the site
http://www.python.org/downloads and click on the
suitable icon
• From the website you can download the suitable
version based
– OS (whether the OS is Windows ,MacOS or Linux)
– the Processor 32 bit or 64 bit.
• For ex: if you are using 64-bit Windows system ,you are
likely to download Windowsx86-64MSI Installer.
• click on the link and download and install the Python
Interpreter.

14. Step-6
• Click on “start menu”
• Go to “Programs”
• Check for “Python 3.7”
• Click on “IDLE(Python 3.7.4 64-bit)”

15. • This Python shell allows us to use Python in
interactive mode.
• The shell waits for a command from the user
,executes it and returns the result.

16. Python Interfaces
• IDLE – a cross-platform Python development
environment
• PythonWin – a Windows only interface to
Python
• Python Shell – running 'python' from the
Command Line opens this interactive shell
• For the exercises, we'll use IDLE, but you can
try them all and pick a favorite
16

17. IDLE
•The only thing to do is that we have to launch
the IDLE program .
• While the Python shell allows the user to work in
interactive mode, the Idle allows to write the
code and save it with .py extension. For Ex:
myProg_py.
• This file is known as Python script.
• Once the program is saved ,it can be executed
either by clicking the Run module or F5.
• If there are no errors you observe the results.
