3. Introduction
 Python is a popular programming
language. It was created by Guido van
Rossum, and released in 1991.
 It is used for:
 web development (server-side),
 software development,
 mathematics,
 system scripting.

4. Python Programming Language is very well suited for Beginners, also for
experienced programmers with other programming languages like C++ and
Java. The biggest strength of Python is huge collection of standard libraries
which can be used for the following GUI Applications (like Kivy,Tkinter, PyQt
etc.)
 Machine Learning
 Web frameworks like Django (used by YouTube, Instagram, Dropbox)
 Image processing (like OpenCV, Pillow)
 Web scraping (like Scrapy, BeautifulSoup, Selenium)
 Test frameworks
 Multimedia
 Scientific computing
 Text processing and many more.

5. About the Project
 For those who do not know, a calculator is
basically a program on a computer that
simulates the behavior of any hand-held
calculator useful for performing
Mathematical Calculations. It is a very basic
device used in our everyday lives. Now all the
smartphones also have a Calculator
application in them.
 While creating any GUI Application there are
mainly two steps:
 The first step is to create a User Interface.
 The second step is the most important one
and in this, to add functionalities to the GUI

6. System Requirement
Environment
 Hardware Requirements :
 RAM
 Processor – intel Pentium 4
 ROM - 256 GB

 SOFTWARE REQUIREMENTS
 Python 2.7 or above
 PyCharm
 A good internent connection
 Linux , MacOS , Windows 7, XP or above

7. Tools and Technplogies
 Tools – Python , PyCharm
 Python Libraries - tkinter, etc.
 Tkinter :- Tkinter is the standard GUI
library for Python. Python when
combined with Tkinter provides a fast
and easy way to create GUI
applications. Tkinter provides a powerful
object-oriented interface to the Tk GUI
toolkit.

8. Pycharm
 PyCharm is an integrated development environment
(IDE) used in computer programming, specifically for
the Python language. It provides a wide range of
essential tools for Python developers and
environment for productive Python, web, and data
science development.
 PyCharm is cross-platform, with Windows, macOS
and Linux versions. Also, Coding assistance and
analysis, with code completion, syntax and error
highlighting, linter integration, and quick fixes.
