  Introduction to Python Python isa versatile, high-level programming language known for its simplicity, readability, and vast ecosystem of libraries and frameworks. It has become a popular choice for a wide range of applications, from web development and data analysis to machine learning and automation.

  Python Syntax andBasic Data Types Syntax Python's syntax is designed to be easy to read and write, with a focus on code readability. It uses whitespace indentation to define code blocks, making it a more intuitive language to learn. Data Types Python supports a variety of built-in data types, including integers, floating-point numbers, strings, booleans, and more. These data types form the foundation for more complex data structures, such as lists and dictionaries. Variables Python variables are dynamically typed, allowing for easy and flexible manipulation of data. Variables can hold values of different data types, and their values can be easily changed throughout the code.

  Control Structures andConditional Statements 1 If-Else Statements Python's if-else statements allow you to make decisions based on certain conditions, enabling your program to take different actions based on the input or state of the program. 2 Loops Python's for and while loops allow you to repeatedly execute a block of code, making it easy to automate repetitive tasks and process collections of data. 3 Conditional Expressions Python's concise conditional expressions, known as "ternary operators," provide a compact way to write simple if-else statements in a single line of code.
• 4.
  Functions and Modules 1Functions Functions in Python allow you to encapsulate and reuse blocks of code, making your programs more modular, maintainable, and efficient. 2 Parameters and Return Values Functions can accept input parameters and return values, enabling you to create powerful, flexible, and customizable functions to solve a wide range of problems. 3 Modules and Packages Python's extensive standard library and third-party packages (modules) provide a wealth of pre-built functionality, allowing you to leverage existing solutions and focus on building your application.
• 5.
  Object-Oriented Programming in Python Classesand Objects Python's object-oriented programming (OOP) features allow you to create custom data types (classes) and instantiate them as objects, which can encapsulate data and behavior. Inheritance and Polymorphism Python's OOP support extends to inheritance, where classes can inherit attributes and methods from parent classes, and polymorphism, where objects can take on different forms. Encapsulation and Abstraction OOP principles like encapsulation and abstraction help you create modular, maintainable, and extensible code by hiding implementation details and exposing only the necessary interfaces.

  Python Libraries andFrameworks NumPy A powerful library for numerical computing, providing support for large, multi- dimensional arrays and matrices, along with a large collection of high-level mathematical functions. Pandas A comprehensive data analysis and manipulation library, offering data structures and data analysis tools for working with structured (tabular, multidimensional, potentially heterogeneous) and time series data. Matplotlib A versatile data visualization library, providing a wide range of tools for creating static, animated, and interactive visualizations, including plots, charts, and graphs. TensorFlow A popular open- source machine learning framework, enabling the development and deployment of complex deep learning models for a variety of applications.
