Python Programming: The Ultimate Beginners Guide!

If you are reading this blog, you must be well acquainted with programming languages. In addition, you must have used them in your programming assignment help & papers. Was professional help necessary in any case?

If you needed professional help with your programming assignments, there’s a big chance that convoluted syntax and the complex nature of working were major problematic factors. Besides these aspects, many students and coders consider factors such as orthogonality (meaningful language features), abstraction, and the programming environment as other vital factors. Programming languages that offer all of these aspects in the best way possible are considered the easiest to learn and the most versatile & powerful among them all.

Python IS one such language!

Why Is Python The Top-Ranking Coding Language of 2022?

Ranked no. 1 in the TIOBE Programming Index of November 2022, Python is one of today’s handiest and most influential programming languages. It finds widespread usage across almost all IT, software, and computer science & programming domains.

• Python is open source and a high-level programming language built on C.
• Developed by Guido Van Rossum in the late 1980s, the Python Software Foundation administers the language currently.
• Python syntax is straightforward to read and like regular English syntax. However, codes are not written in machine-readable codes and thus need to be converted & processed before they can be executed.
• The language is interpreted in nature and supports multiple programming paradigms. For example, Python supports object-oriented programming, functional programming, and procedure-oriented paradigms.

The primary objectives behind the design of any programming language are more effortless coding, improved productivity, seamless integrations, flexibility, adaptability & scalability, and faster executions. All languages are designed with the above factors, finding applications through the years until superseded by a better language. In that way, programming languages are born and then gradually become obsolete.

Python has stood the test of time. First developed in the 1980s, it is still a living and thriving language more than 30 years later. It offers all of the above and performs better than most competitors.  

Python is the best choice whether you are just starting or looking to pivot to a new programming language. Network programming, web development, software programming, data science, machine & deep learning—the prospects of a Python programmer are genuinely immense.

Setting Up Python

One of the first things anyone must do is install Python in their system. This article assumes you are using Windows OS. If so, then here are the following steps to take.

[NOTE: You will need to be able to use Windows PowerShell. PowerShell is a specialized version of the Windows Command Prompt and is necessary to install Python in Windows.]

1. The latest stable release of Python For Windows is Python 3.11.0. Visit Python 3 is currently the only prominent version, and Python 2 is no longer actively supported by The Python Software Foundation.
2. Once the setup finishes downloading, double-click on the file to run it. You can customize the installation and choose the additional feature to be added.  
3. One key thing to note while installing Python to your Windows PATH variable. The PATH variable directs Windows to the directories whose files must be executed on start-up. Therefore, adding Python’s install directories to Windows PATH allows easy inclusion of directories for any additional packages and libraries to be installed.

Modern Python installers provide the option to add Python & its components automatically to the Windows PATH environment variable.

4. Once installed, run Power Shell and type PYTHON. This activates thePython interpreter or

Using a Python IDE or Text Editor

You can execute commands one after another in the Python shell. For that, you will need a code editor or integrated development editor. There are numerous editors and IDEs, and the Python source file comes with one. IDLE (Integrated Development U& Learning Environment) is great for beginners, but we recommend Notepad++ or Visual Studio Code.

Now, it is time to dive into the technicalities of Python Programming.

The Basics of Python

Keywords

All programming languages have their reserved keywords, and Python is no different. When you enter keywords in the Python interpreter, it executes a specific command.

Some of the significant keywords in Python are:

Some of the most common keywords in Python are:

• AND
• For
• If
• Lambda
• NONE
• Non-Local
• TRUE
• FALSE
• Return
• While
• OR
• Try
• Pause
• Break
• Continue
• Def
• Else
• Del
• With
• Global
• From
• Class
• Elif

Operators

Mathematical, relational, and Boolean operations are fundamental to every language. In addition, Python supports all kinds of simple and advanced mathematical operations through external libraries such as NumPy.  

Here are some of the most commonly-used used operators across different types of Python programming:

• + àAddition
• – àSubtraction
• * àMultiplication
• / àDivision
• % àModulus Division
• ** àExponentiation
• // àFloor Division
• = àEqual
• ! = àNot equal to
• >  àGreater than
• < àLesser than
• >= àGreater than equal to
• <= àLesser than equal to
• In àReturns 1, if the specified value is present in a collection
• Not In àReturns True if a specific value is NOT present in a collection
• Is àTrue if two variables point to the same object
• It is Not àTrue if two variables DO NOT point to the same object
• & àAND
• | àOR
• ^ àXOR
• ~ àNOT

Indentations & Dynamically-Typed

Indentations replace the curly braces of C, C++, and java, three of Python’s closest relatives. Indenting is critical in Python and defines scope & access. Also, unlike its relatives, Python does not use semicolons to end statements.

Python is a dynamically-typed language. Therefore, you do not need to mention the data type precisely; the language infers it from the value entered.
