Python Introduction

Python is a popular, high-level programming language known for its simplicity, readability, and flexibility. It is widely used in a variety of applications, including web development, data analysis, scientific computing, and artificial intelligence.

One of the key features of Python is its dynamic, strongly typed nature, which means that you don’t have to specify the type of a variable when you declare it, and the type of a variable can change at runtime. This can make Python code easier to write and maintain, but it can also make it harder to debug if you make a type-related mistake.

Here are some basic concepts in Python:

  • Variables: In Python, you can use variables to store and manipulate data. To create a variable, you simply give it a name and assign it a value using the “=” operator. For example:
  • Data types: Python has several built-in data types, including integers (e.g. 1, 2, 3), floating point numbers (e.g. 3.14, 1.6), and strings (e.g. “hello”). You can use the type() function to determine the type of a variable.
  • Operators: Python has a variety of operators that you can use to perform operations on variables. For example, you can use the “+” operator to add two numbers, or the “*” operator to multiply them.
  • Loops: In Python, you can use loops to execute a block of code multiple times. There are two main types of loops: for loops, which allow you to iterate over a sequence of elements, and while loops, which allow you to execute a block of code as long as a certain condition is true.
  • Functions: In Python, you can define your own functions to encapsulate pieces of code that you want to reuse. To define a function, you use the def keyword, followed by the function name and a list of arguments in parentheses. For example:
