Introduction to Python

What is Python

  • Python is a high-level, easy-to-learn programming language that is used to give instructions to the computer in a simple and human-readable language.
  • It is used to create programs, application software, mobile applications, games, websites, and even AI.
  • Python is one of the most versatile and widely-used programming languages.
  • Python works on all devices (Windows, Linux, Mac).
  • Python is used by all beginner programmers or highly professional programmers.
  • Python is a case-sensitive language
  • History of Python

  • First Public released in 1991.
  • The father of Python was Guido Van Rossum.
  • In 2000 Introduced Major Feature like.
    1. Garbage Collection
    2. Unicode Support
    3. List comprehension
  • In 2008 Introduced Major Feature like.
    1. Clean, more consistent syntax
    2. Better Unicode Handling
    3. Improved Libraries
  • Why learn Python

    Easy to read and write and Learn :

    Python has clean and readable code just like the English language.

    Automate Task :

    Python can Automate or we can say automatically manage repetitive works like
  • Data Entry
  • Email sending
  • SMS Sending
  • Report Generation
  • File Handling
  • Web Scraping and many more
  • Huge Demand in industry :

    Almost all leading companies use python programming language for their product or Application or Software Development. Companies like
  • Google
  • Netflix
  • Spotify
  • Dropbox and many more.
  • So, this creates strong career opportunities for IT Developers.

    Great for Beginners and professionals also :

    By using Python Programming Language developers can create by starting school projects to high level Real-World Enterprise Applications Projects.

    OpenAIOdd or Even Game
    GoogleSimple Chatbot

    Huge Community Support :

    Python use by the global community. So, you easily find
  • Tutorials
  • Documentation
  • Open Source Projects
  • Development Time :

    Python has a large ecosystem of libraries that save developer time of development of any application. Some Libraries are
  • OpenCV for Image Processing.
  • Scikit-learn for Machine Learning.
  • Matplotlib for Graphs and Charts
  • Features of Python

    Web Development :

    refers to its ability to build powerful, secure, and scalable websites and APIs efficiently using robust frameworks like Django and Flask.

    Simple and Easy Syntax :

    Python uses clean, readable code that looks like plain English, making it incredibly easy to learn and write.

    Platform Independent :

    You can run the exact same Python code on Windows, macOS, or Linux without making any changes to it.

    High Level Language :

    Python manages complex computer tasks like memory allocation automatically, letting you focus entirely on writing your logic.

    Object-Oriented Programming(OOPs) :

    It allows you to organize code into reusable blocks called "objects" that mirror real-world items and structures.

    Interpreted Language :

    Python executes code line-by-line, which means it runs instantly without a separate compilation step and makes finding errors a breeze

    Advantages of Python

  • Easy to Learn
  • Less Code faster Development
  • Large Library Support
  • Cross Platform Support
  • Open Source and free
  • Integration with other languages
  • Disadvantages of Python

  • Slow Execution Speed
  • Poor Mobile Development Support
  • High Memory Consumption
  • Lack of Compile-Time Type Checking
  • Applications of Python

  • Artificial Intelligence
  • Robotics
  • Cloud Computing
  • Data Engineering
  • Machine Learning
  • Python Example Program

    Here are some simple examples of Python Programming Language
    Example 1 : Simple Print Hello
                print("Hello World..")
                
       Output
                Hello World..
    Example 2 :Simple Calculator
                a=10
                b=5
                print("Addition of A and B is", a+b)
                print("Subtraction of A and B is ", a-b)
                
       Output
                Addition of A and B is 15 
                Subtraction of A and B is 5
