Python tutorial for the absolute beginners

   Introduction to Python     

    Before we are diving to the python programming, let's discuss about programming and programming languages. What is a programming language and why we need it? The simple answer is, the programming language is a way to communicate with the computer/machine just like how we humans use various languages to communicate with each other.

    So, what kind of language is known to the computer/machine? The computer knows the binary (1s and 0s). So, wanna learn a language that consists of only 1s and 0s? No, no, no..! absolutely no..! But, how we can communicate with the computer/machine? The programming language is consists of human-readable words and known as high-level programming languages. But, obviously, it is not like (very likely) normal human languages. It follows some rules and syntaxes. But, I promise you, it is very easy to learn. 

    If we are using a language that does not consist of 1s and 0s, how the computer can understand the language? There is an intermediator between our program and machine who handle the job of converting our human-readable language (program code) to a machine language (binary). It is known as a compiler/interpreter. The process of converting the code to machine language is known as compiling. Once our code is get compiled, there will be an outcome of a compiled file (the file type depends upon the language we've used). 

    Now, all we know, what is programming languages. Now let's discuss about Python programming. 

     Python is a popular programming language that is widely used in industry and academia. It is a high-level, dynamically-typed language that is easy to learn and powerful to use. Some of the features that make Python popular are:

1. It has a simple and readable syntax, which makes it easy to write and understand code.
2. It is dynamically-typed, which means that you don't have to specify the data type of a variable when you declare it.
3. It has a large standard library that provides many useful functions and modules for tasks such as connecting to web servers, reading and writing files, and working with data.
4. It has a large and active community of users, which means that there are many resources available online for learning and using Python, and there are also many third-party libraries and frameworks available for use.

    

    Python is used in many different areas, including web development, scientific computing, data analysis, and artificial intelligence. It is a versatile language that can be used for a wide range of tasks.

     Here is a simple Python program that will print "Hello, World!" to the console:

print("Hello, World!")

     To run this program, you will need to have Python installed on your computer. You can then open a terminal or command prompt, navigate to the directory where you saved the file, and run the following command:

python file_name.py

This will execute the program and print "Hello, World!" to the console.
