Python Tutorial for Beginners:- A Comprehensive Guide

Python is one of the most popular programming languages used today. It is easy to learn and use, but it’s also powerful enough to build complex applications that are capable of running on a variety of devices. In this tutorial series, I’ll show you how to write your own programs in Python so that you can learn more about this great language! Python Tutorial for Beginners:- A Comprehensive Guide

What Is Python?

Python is a high-level programming language, which means that it’s easier to learn than most other languages. It has many features that make it an excellent choice for beginners:

  • Python can be used as a general-purpose language, or to solve specific problems in various fields. You’ll find its flexibility useful if you have to develop apps for multiple platforms or if you need to work with large amounts of data (like databases).
  • Python is an interpreted language — meaning that when you type commands into the interpreter window inside of your terminal application (on Mac OS X), they’re executed immediately without compiling first. This makes debugging easier because every step of execution is visible at once; however, this also means that programs written in pure Python won’t run like they do in compiled languages such as C++ or Java until they’ve been executed by someone else who knows how things work under the hood!

Benefits of Python

Python is a high-level, general-purpose programming language that was designed with simplicity in mind. The Python community has developed many libraries and extensions to the core language that make it an extremely versatile tool for developing applications.

Python is free and open source, so you don’t need to worry about paying for licenses or downloading software from the internet—which means you can focus on learning instead of worrying about how much money your computer needs!

It also has built-in support for object orientation (OO), which makes it easy to write reusable code without having to write any boilerplate code first; this makes your programs more flexible than those written in other languages such as C++ or Java because they allow users access across different areas within their application without having any special knowledge required beforehand (such as knowing what methods exist).

Setting Up Python

If you’re new to Python and want to use it for your first project, the best way to get started is with an IDE (integrated development environment). There are many IDEs out there that can help you code in Python.

You’ll need Anaconda, which comes pre-installed with all of the tools needed for working with Python 3.7. You can download this from here:

Then install Spyder IDE from here:

Variables and Data Types in Python

You can use variables to store values, and the data type of a variable determines what kind of value it can store. The following types are available in Python:

  • Strings – A sequence of characters (e.g., “Hello”)
  • Integers – Numbers with no fractional part or decimals (e.g., 2)
  • Floats – Numbers with decimal points or scientific notation (e.g., 3.14)

In order to assign values to these variables, you need to specify their types when you declare them in your program code by using a colon before the variable name: For example: “string”, int64_t

Python Operators

Python has many operators. The most common mathematical operations that you will use in your Python code are the arithmetic operators, bitwise operators and comparison operators.

The following table shows all of these operators:

  • Operator Description Type Description Example

+ Addition + # sum = 5 + 3 = 8

/ Divide (only on integers) // Divide remainder by power of 2 to get more digits in a number

Conditional Statements in Python

Python supports the following conditional statements:

  • if statement
  • elif statement
  • else statement (optional)

Loops in Python

For loops

The for loop is used to iterate over a list or other collection of objects, and execute statements for each item in the list. For example:


# The script below does nothing but call a function named print_list(), which prints out all items in an array. It uses three variables: a, b and c (which hold the values 1, 2 and 3). These are initialized with random numbers from 0-9 before running this program.

# The first line in this script sets up an empty array with two elements named a and b respectively; these will contain our results after running through our looping code later on down below

Functions in Python

In Python, functions are also called methods. A function is a named block of code that you can use in your program to perform an action. In Python, there are two ways to create functions:

  • Defining a function individually in the code (function definition)
  • Using def statements with parameters for passing arguments into the newly defined function. This can be done with either single values or lists containing multiple values and then assigning them within the body of your new function (named block).

Modules in Python

Python modules are files containing Python code. They can be imported into other programs, and then used in them. Modules are useful for organizing your code and making sure that you don’t have to type the same code twice.

To import a module, you should use the import keyword:

import module_name

Files and Exceptions in Python

Python has a lot of built-in functions, but most of them can be used in the same way as they would if they were written out. To use a function, you need to import it into your program and then call it on its name. Python Tutorial for Beginners:

To import a module, use the following command:


You’ll see an error message if there’s an error with importing your file:

>>> import Traceback (most recent call last): File “” , line 1 , in NameError : name ” is not defined

With the right tools, you can learn to code at home.

Python is a popular programming language that’s easy to learn and free. It has an active community of developers, who are constantly creating new tools and applications for the language. Python is open source, meaning anyone can read its code or contribute changes back into its development process.

Python’s large community means you don’t have to be an expert in order to create useful projects with it—but if you want more power than what Python has built-in (which includes support for text processing), there are plenty of third-party libraries available for download online as well!

I hope that this tutorial has given you a good foundation for learning Python. It’s an amazing language that can do so much and it makes programming accessible to anyone. There are many great resources out there if you want to learn more, but if all you need right now is a way to create your own programs then I recommend checking out my book The Complete Python Crash Course (affiliate link).
