Introduction to python .

 Overview of Python:

Python is a high-level, interpreted programming language that was first released in 1991. It is a versatile language that can be used for various purposes such as web development, scientific computing, data analysis, artificial intelligence, and more. Python is known for its readability, simplicity, and ease of use.

Installing and setting up Python:

To install Python, you can download the installation file from the official Python website (https://www.python.org/downloads/). After downloading, run the installer and follow the instructions to complete the installation.

Running Python code using Jupyter notebook:

Jupyter notebook is a web-based interactive development environment that allows you to write and run code in a web browser. To run Python code using Jupyter notebook, you first need to install Jupyter notebook. This can be done using the following command in the command prompt:

Copy code

pip install jupyter

After installing, you can start a Jupyter notebook by running the following command:

Copy code

jupyter notebook

This will open a web browser with the Jupyter notebook interface, where you can create and run Python notebooks.

Basic data types and variables:

Python has several built-in data types, including:

Numbers (integers, floats, complex numbers)

Strings

Booleans

Lists

Tuples

Dictionaries

Sets

Variables are used to store data in Python. To create a variable, you can simply assign a value to a name using the '=' operator. For example:

makefile

Copy code

x = 5

This assigns the value 5 to the variable x. You can also assign values to multiple variables at once using the following syntax:

Copy code

x, y, z = 1, 2, 3

This assigns the values 1, 2, and 3 to the variables x, y, and z, respectively.

Operators and expressions:

Python supports several types of operators, including:

Arithmetic operators (+, -, *, /, %, **)

Comparison operators (==, !=, <, >, <=, >=)

Logical operators (and, or, not)

Bitwise operators (&, |, ^, ~, <<, >>)

Assignment operators (=, +=, -=, *=, /=, %=, **=, //=)

Expressions are combinations of operators and operands that produce a value. For example:

makefile

Copy code

x = 5

y = 3

z = x + y

This assigns the value 8 to the variable z, which is the result of adding the values of x and y.
