  Introduction to Python Pythonis a high-level, interpreted programming language known for its readability. It was created by Guido van Rossum and released in 1991. Python is widely used in web development, data analysis, artificial intelligence, and automation.

  Installing Python You candownload Python from the official website python.org. The installation process varies slightly depending on your operating system. After installation, you can verify it by opening a command prompt and typing `python --version`.

  Basic Python Syntax Pythonuses indentation to define code blocks, such as loops and functions. Comments are written with the `#` symbol and are used for explaining code. Python code is case-sensitive, meaning variables like `MyVar` and `myvar` are different.
• 5.
  Variables and DataTypes Variables in Python are created when you assign a value to them, without declaring their type. Common data types include integers, floats, strings, booleans, and lists. Python is dynamically typed, so variables can change their data type during execution.
• 6.
  Control Structures `if`, `elif`,and `else` statements are used to make decisions in code. Loops like `for` and `while` enable repetitive execution of code blocks. Proper indentation is essential for control structures to function correctly.
• 7.
  Functions in Python Functionsare blocks of reusable code defined using the `def` keyword. They can accept parameters and return values to make code more modular. Python also includes many built-in functions like `print()`, `len()`, and `range()`.

  Working with DataCollections Lists are ordered, mutable collections for storing multiple items. Tuples are similar to lists but are immutable. Dictionaries store data in key-value pairs and are useful for quick lookups.
