Python Tutorial Basic

Python is a high-level, interpreted programming language that is widely used for web development, data analysis, artificial intelligence, and scientific computing. It is a general-purpose language, which means it can be used to build just about anything, which is why it is so popular.

To get started with Python, you will need to have it installed on your computer. There are a few different ways to install Python, but the easiest is to download the Python installer from the official Python website and run it.

Once Python is installed, you can start using it in one of two ways:

Interactively: You can open up a Python interpreter and start typing code into the interpreter directly. This is a great way to play around with Python and see what it can do.

Write a script: You can write a script (a file containing Python code) and run it. To do this, create a new file with a .py extension and write your code in the file. Then, you can run the script using the Python interpreter.

Here is a simple example of a Python script that prints "Hello, World!" to the console:

print("Hello, World!")

To run the script, open up a terminal or command prompt and navigate to the directory where you saved the script. Then, type python script.py, where script.py is the name of your script.

In addition to the print function, here are a few other basic Python concepts to get you started:

Variables: You can store values in variables and use them later in your code. For example:

x = 10

y = 20

print(x + y) # prints 30

Data types: Python has a few different built-in data types, including integers, floating point numbers, and strings. For example:

x = 10 # an integer

y = 20.5 # a floating point number

z = "Hello, World!" # a string

Lists: You can store a collection of values in a list. Lists are indexed, which means you can access the values in a list by their position (also known as their index). Lists are created using square brackets. For example:

my_list = [1, 2, 3, 4]

print(my_list[0]) # prints 1

print(my_list[1]) # prints 2

Dictionaries: Dictionaries are similar to lists, but instead of being indexed by a number, they are indexed by a key. Dictionaries are created using curly braces. For example:

my_dict = {'a': 1, 'b': 2, 'c': 3}

print(my_dict['a']) # prints 1

print(my_dict['b']) # prints 2

There are many more advanced concepts in Python, but these should be enough to get you started. Happy coding!
