🐍Day 13- Basics of Python

🐍What is Python ?

Python is a versatile and powerful programming language loved by beginners and experts alike. It's like a Swiss Army knife for coding because it can handle a wide range of tasks, from simple scripts to complex applications.

Imagine Python as a friendly language that speaks human-like syntax. Just like how you'd give instructions to a friend, you can tell Python what you want it to do, step by step, using plain language.

Here's a breakdown of why Python is so popular:

1. Readable Syntax : Python's syntax is clean and easy to understand, making it accessible for beginners. You don't need to be a coding genius to grasp its concepts.

2. Versatility : Python can be used for almost anything: web development, data analysis, artificial intelligence, automation, scientific computing, and more. It's like having a universal tool for various programming tasks.

3. Cross-platform : Python runs on different operating systems like Windows, macOS, and Linux, ensuring your code works regardless of the environment.

4. Vibrant Community : Python has a massive community of developers who contribute libraries, frameworks, and tutorials. If you ever get stuck, there's always someone willing to help.

5. Interpreted Language : Unlike languages like C++ or Java, Python doesn't need to be compiled before running. You can write code and execute it line by line, which accelerates development and debugging.

6. Rich Ecosystem : Python boasts a vast ecosystem of third-party libraries and frameworks that simplify complex tasks. Whether you're building a website with Django, analyzing data with Pandas, or creating neural networks with TensorFlow, there's a library for almost everything.

🐍How to Install Python ?

Installation of Python in Linux (Ubuntu):

Step 1 : Open Terminal First things first, let's fire up the Terminal. You can do this by searching for "Terminal" in your application launcher.

Step 2 : Update Package Lists It's always a good idea and best practice to ensure your package lists are up to date before installing anything. Run the following command:

sudo apt-get update
Or                          #Both will Work
sudo apt update

Step 3 : Install Python Ubuntu typically comes with Python pre-installed, but we'll ensure we have the latest version. Run the following command to install Python 3:

sudo apt-get install python3

This command will install Python 3 and its dependencies. Once the installation is complete, you can verify the installation by typing:

python3 --version

🐍Different Data Types in Python

• Primitive Data Structures

  you will say what is Primitive which can't be break further.

1. Integer (int): Represents whole numbers without any fractional part.

     apples = 25   #int
   

2. Float : Represent real numbers with decimal point.

    Marks = 60.5   #float
   

3. String (str): Represents a sequence of characters. Single alphabet or character is enclosed within (' ')single inverted comma and A sequence of chracters enclosed within (" ")Double inverted comma .

     name = "Vivek"
    sing = 'V'
   

4. Boolean (bool): Represents either True or False.

    x = true
    y = false
   

• Non primitive Data structures

1. List(list) : Represents an ordered and sequential collection of items.It is heterogeneous means can store different data types. and it is mutable(can be changed).

    list_of_fruits = ["Banana",1,2,3,true,false] #This Method of Creating list is faster
    print(list_of_fruits)
   
    #Another way of making list is using function
   
    list_of_names = list() #this method will call the class
    print(type(list_of_names))
    ***********************************************************
    OPERATIONS IN LIST
    - append
    -clear
    -count
    -extend
   

2. Tuple (tuple): Similar to lists, but immutable (cannot be changed once created).

     fruits = ("banana", "papaya")
   

3. Dictionary (dict): Represents a collection of key-value pairs. Keys are always unique within a dictionary.

     d1 = {"name": "Vivek",
           "role": "Dev", 
           "city": "Pune"
          }
   

4. Set (set): Represents an unordered collection of unique items. Duplicates are not allowed.

     numbers = {1, 2, 3,}
   

   🚧Conclusion

   In wrapping up, understanding Python's various data types is like having a reliable map for your coding journey 🗺️. Each type has its own role, from numbers to text and more, helping you navigate through your programs with ease. So, embrace these tools, and let them guide you to success in your coding adventures! Happy coding! 🚀🐍😊

Happy Learning😊
