Guido van Rossum’s Code Examples in a Python Tutorial
In Python, white spaces or indentation are utilized to specify the scope in a code. To install Python on windows, open any browser on your windows, use the link https://www.python.org, click for the latest Python3 release, download and run the executable .exe installer, and verify that Python has been successfully installed on windows. Code editors are tools that are lightweight and used to write and edit code.

Python 101: The Ultimate Python Tutorial For Beginners
INTRODUCTION
Python is a versatile, high-level programming language that emphasizes code readability through the use of significant indentation and a clear, logical approach to object-oriented programming. Python programs are typically saved with a .py extension and can be applied to a wide range of applications, including machine learning and AI, automation, image processing, scientific computing, web development, and database management. Since its inception in the late 1990s by Guido Van Rossum as a successor to the ABC programming language, Python has evolved significantly. It was first released in 1991 as Python 0.9.0 and later introduced features such as list comprehension, garbage collection, reference counting, and Unicode support with the release of Python 2.0. Python 3.0 was subsequently released, and the language remains popular due to its flexibility, productivity, supportive community, and ease of use.
Guido Van Rossum believes that having advanced tools that provide a clearer view of the software’s structure would be of great benefit, as he hopes for a more efficient approach.
PYTHON ENVIRONMENT
To begin using Python, you can choose from two main distributions — MSDTHOT #1 and Anaconda. The first step in using any programming language is to learn how to install it on your system. For Windows users, follow these steps: 1. Open any browser on your Windows machine. 2. Use the link https://www.python.org to access the Python website. 3. Click on the latest Python3 release. 4. Download and run the executable .exe installer. 5. Finally, verify that Python has been successfully installed on your Windows machine.
PYTHON IDEs AND CODE EDITORS
Code editors are lightweight tools used for writing and editing code. However, when dealing with larger and more complex programs, testing and debugging become necessary. In such instances, IDEs come in handy compared to editors. They allow you to write, test, and debug simultaneously, making it easier to understand your code. Popular examples of such environments include Sublime Text 3, Atom, Thonny, Pycharm, Visual Studio Code, and vim. To get started, simply download and run the installer like any other program. Once installed, you’re ready to start coding. Let’s begin by writing a «Hello, world!» program. In Python, we use the print() function to print out something.
#Running our first program print("Hello, world!") To execute the code, it must first be saved with the «.py» extension to indicate that it is a Python code. Therefore, before running the program, it is necessary to save it with the name «Hello.py».
Have you successfully executed your first program? If so, congratulations are in order!
FUNDAMENTALS OF PHYTHON
Here are a few fundamental concepts in Python that beginners should comprehend.
Python is a programming language that prioritizes readability. It achieves this by using English keywords instead of punctuations, such as «and», «as», «assert», «async», «await», «break», «class», and «def». Additionally, it avoids cluttered formatting and does not require curly brackets or semicolons to indicate blocks or statements.
In programming, data or values can be stored using a variable. For instance,
Variables a and b hold the values 10 and 0.5 in Python. Literals, such as 10 and 0.5, are used to represent fixed data in its raw form.
Python programming is simplified with the use of data types, which are defined as a set of values and their accompanying operations. In Python, there are several data types available, including Numeric Types such as int, float, and complex; Sequence Types such as list, tuple, and range; Set Types like frozen and set; Mapping Types such as dict; and the Boolean Type, which is represented by bool.
Comments are helpful in making the code understandable by describing what’s going on inside a program. These comments are ignored by the Python interpreter. To write a single-line comment, use the ‘#’ symbol. Other types of comments include multi-line comments and doc-string comments.
#This is a comment, not executed a = "Hello World" # a contain "hello world" A string literal A unique symbol, known as an operator, is responsible for performing arithmetic or logical functions like addition and multiplication.
a = 10 b = 20 sum = a + b print(sum) # Output: 30 Diverse categories of operators exist, among which are Arithmetic Operators. These perform various mathematical operations such as addition, multiplication, subtraction, division, quotient calculation, remainder calculation, and exponentiation. For instance, the + operator sums operands, while the * operator multiplies them. Similarly, the — operator subtracts operands, / operator divides the left operand by the right, // operator finds the quotient, and % operator gives the remainder of the division. Lastly, ** operator raises the right operand to the power of the left operand.
a = 2 b = 5 result = a**b # 2 raised to the power of 2 print(results) #output: 32 The first operator is the assignment operator. In addition, there are logic operators such as Logic AND, Logic OR, and Logic NOT. Lastly, comparison operators are utilized to compare two values.
In contrast to many programming languages that use curly-brackets, Python employs white spaces and indentation to establish the scope in a code.
Loops are utilized to iterate over an object and can be classified as either while loops or for loops. The latter is specifically designed to iterate through a collection of items. For instance, consider the following example.
languages = ['Python', 'C++', 'PHP'] for item in languages: print(item) #output: Python C++ PHP The while loop enables the execution of a specific set of instructions until the condition specified is met. As an example, consider the following:
A constant is a type of variable that stores values that cannot be altered. In Python, constants are seldom utilized.
CONCLUSION.
This guide aims to introduce you to the Python programming language. We began by understanding Python and the installation process, followed by writing our initial code and exploring some basic Python fundamentals. Python programming encompasses much more than what we have covered here. Thank you for taking the time to read this.

Python Tutorial by Guido van Rossum
Description:
Python is an easy to learn, powerful programming language. This tutorial introduces the reader informally to the basic concepts and features of the Python language and system. This tutorial does not attempt to be comprehensive and cover every single feature, or even every commonly used feature. Instead, it introduces many of Python’s most noteworthy features, and will give you a good idea of the language’s flavor and style.
