- 2. Introduction
- 3. What is Python…? Python is a general purpose programming language. Python is a versatile and widely-used high-level programming language known for its simplicity and readability. Python emphasizes code readability, making it easy for beginners and experienced developers to write clear and logical code. Python is dynamic. Python is also called as Interpreted language
- 4. Python supports multiple programming paradigms, including procedural, object- oriented, and functional programming. Its syntax is clean and easy to understand, with fewer lines of code required compared to other languages. This makes it ideal for rapid development
- 5. History Invented in the Netherlands, early 90s by Guido van Rossum Python was conceived in the late 1980s and its implementation was started in December 1989 Guido Van Rossum is fan of ‘Monty Python’s Flying Circus’, this is a famous TV show in Netherlands Named after Monty Python Open sourced from the beginning

- 7. Key Features of Python Python is a high-level, interpreted programming language known for its simplicity and readability. Simple and Readable: Python's syntax is designed to be easy to understand and write, making it an excellent choice for beginners and experienced programmers alike. Interpreted Language: Python code is executed line by line, making debugging easier and eliminating the need for a compilation step. Dynamic Typing: You don’t need to declare data types explicitly; Python determines the type of variable during runtime. Versatile and Portable: Python runs on multiple platforms, including Windows, macOS, Linux, and more. It can be used for web development, data analysis, artificial intelligence, automation, and much more.
- 8. Extensive Libraries and Frameworks: Python has a rich ecosystem of libraries (like NumPy, Pandas, TensorFlow) and frameworks (like Django, Flask) that simplify development in various domains. Python is widely used in web development, data science, machine learning, automation, scientific computing, and more. Cross-platform: Python can run on various operating systems, including Windows, Linux, and macOS. Community support: Python has a large and active community, offering resources like tutorials, forums, and open-source libraries.
- 9. Why do people use Python…? The following primary factors cited by Python users seem to be these: Python is object-oriented Structure supports such concepts as polymorphism, operation overloading, and multiple inheritance. Indentation Indentation is one of the greatest future in Python. It's free (open source) Downloading and installing Python is free and easy Source code is easily accessible
- 10. EXAMPLE if condition: # This is inside the if block print("Condition is true") if nested_condition: # This is a nested block inside the if block print("Nested condition is also true")
- 11. It's powerful - Dynamic typing - Built-in types and tools - Library utilities - Third party utilities (e.g. Numeric, NumPy, SciPy) - Automatic memory management It's portable - Python runs virtually every major platform used today - As long as you have a compatible Python interpreter installed, Python programs will run in exactly the same manner, irrespective of platform.
- 12. It's mixable - Python can be linked to components written in other languages easily - Linking to fast, compiled code is useful to computationally intensive problems - - Python/C integration is quite common It's easy to use - No intermediate compile and link steps as in C/ C++ - Python programs are compiled automatically to an intermediate form called bytecode, which the interpreter then reads - This gives Python the development speed of an interpreter without the performance loss inherent in purely interpreted languages It's easy to learn - Structure and syntax are pretty intuitive and easy to grasp
- 13. Installing Python Python is pre-installed on most Unix systems, including Linux and MAC OS X But for in Windows Operating Systems , user can download from the https://www.python.org/downloads/ - from the above link download latest version of python IDE and install, recent version is 3.4.1 but most of them uses version 2.7.7 only
- 14. After installing the Python Ver#2.7.7, go to start menu then click on python 2.7 in that one you can select python (command line) it is prompt with >>>
- 15. Where uses python … Web frameworks and applications. GUI based desktop applications. Graphics design, image processing applications, games, scientific applictions. ML, AI, neural networks. Data science and data visualization. IOT Database development..
- 16. What can I do with Python…? System programming Graphical User Interface Programming Internet Scripting Database Programming Gaming, Images, XML , Robot and more
- 17. Enough to understand the code Indentation matters to code meaning - Block structure indicated by indentation First assignment to a variable creates it - Variable types don’t need to be declared. - Python figures out the variable types on its own. Assignment is = and comparison is == For numbers + - * / % are as expected - Special use of + for string concatenation and % for string formatting (as in C’s printf) Logical operators are words (and, or, not) not symbols The basic printing command is print
- 18. Python Code Execution Python’s traditional runtime execution model: source code you type is translated to byte code, which is then run by the Python Virtual Machine. Your code is automatically compiled, but then it is interpreted. Source code extension is .py Byte code extension is .pyc (compiled python code)
- 19. Anaconda Navigator • Anaconda Navigator is a desktop graphical user interface (GUI) included in Anaconda® Distribution that allows you to launch applications and manage conda packages, environments, and channels without using command line interface (CLI) commands. Navigator can search for packages on Anaconda.org or in a local Anaconda Repository. • It is available for Windows, macOS, and Linux.
