5 Reasons why python should be beginners' first choice.

Python is an interpreted, open-source, high-level, general-purpose, programming language. It was created by GUIDO VAN ROSSUM and was released in 1991. It emphasized on code readability with its notable use of significant white space. Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects. Python is often described as a “batteries included” language due to its comprehensive standard library. Factors like readability use of white space and a wealth of excellent documentation and communities make python easier for beginners to learn.


1. PYTHON SYNTAX

Syntax refers to the structure of the language. They are simple and easy to learn which have led it to be embraced by beginners and experts alike. The cleanliness of python’s syntax has led some to called it “executable pseudocode”. Since there are many similarities between the syntax of Python and other languages but from my personal experience, I can say that its easier to read and understand a Python script than to read a similar script written in C, C++, Pearl or JAVA.

Python programs are executed in two different modes.

i. Interactive Mode Programming

It is the common line shell that provides the interpreter without passing a script file as a parameter. Let us print a sentence “I love my country” in interactive mode. If you are using the new version of Python, you would need to use print statement with parenthesis as in print (“I love my country”);

Since I am using the version 2.7.15. Here is the output:



ii. Script Mode Programming


The “normal mode” is the script mode and ends with a .py file and runs through the interpreter of Python. In this mode we can run all the codes in a single file.

Python Identifiers

A python identifier usually is a variable, a function, a class, a module or it can be any other object. You can give a name to the entity in Python, it is called an identifier. A valid identifier starts with a letter (A-Z, a-z) or an underscore which can be followed by a zero, letters, underscores, or numbers (0-9).

Types of identifiers

• Variable

• Function

• Class

• Module

Let’s go and check what keywords are available in Python.

Python Syntax Basics-Keywords

To know what are the Python keywords, open your IDE and type the following










The output should be something like this







These keywords may change as new Python versions are released. Two things should be kept in mind:

• They are fixed and cannot be used as identifiers.

• They are case sensitive.

Python Statement

Before you go ahead with the Python Syntax you should know basics in Line and Indentation.

Indentation makes the code easier to visually scan, understand, and makes the code clean. The space that goes under indentation varies under each situation




The output of this code is shown below:-










NOTE: for “for” statement it has one space, and “if” has two. That establishes a hierarchy of what’s happening within the code.

For “for” statement:-




The output is shown below:-













For “if” statement:-













The output is shown below:-





In comparison to other programming languages, its code is relatively easy to read as it resembles a part of everyday English that we speak.

For example, the following is a code that literally tells the computer to print

“STAYING HOME, SAVES LIVES”

WHEN IN PYTHON


print ( “STAYING HOME, SAVES LIVES” )


WHEN IN JAVA

public class My JAVA program{

public static void main(String args[]){

System.out.print.ln ( “STAYING HOME, SAVES LIVES” );

}

}


WHEN IN C++

# include<iostream>

using namespace std;

int main ()

{

count << ”STAYING HOME, SAVES LIVES”;

return 0

}


So isn’t it easy compared to other languages? So, beginners what are you thinking about, go for it.


2. PYTHON LIBRARIES

Libraries are a collection of function and methods, that allows you to access in already implemented logic in the form of variables thus preventing the loss of production man-hours in doing something that has already been done.

Earlier, people performed Machine Learning tasks by manually coding, algorithm through mathematical and statistical formulation. This made the processing time extremely consumable. If you are interested in web development, data science, Artificial Intelligence (AI), game development, etc there are libraries that will save you ample time in development.

Some of the libraries that you must know are NumPy, data, scipy, pandas, etc. all these will help you to do a lifetime small trick in data transformation function.

Python libraries also included areas like internet protocols, string operation, web services tools to support the OS interface

3.OPEN SOURCE

Open-source software is computer software where source code is made publicly available for modification and enhancements.

Python language is developed under Open Source Initiative (OSI) approved open source license and copyrighted under a GPL-compatible license, which makes it free to use and distribute including for commercial purposes.

There are many enthusiasts who simply believe that code should be open.

The main reason why developers go for free-for-modification projects is to be recognized, to sharpen their programming skills, and to become a part of the vibrant community. You can also make a great resume that stands out of the crowd.


4. MEMORY ALLOCATION

A software developer should always keep in mind the importance of memory management. There are two types of memory allocation. They are:

Static memory allocation: The program is allocated memory at compile time. An example of this would be in C/C++. The stack is used for implementing static allocation. In this case, memory cannot be reused.

Dynamic memory allocation: The program is allocated memory at run time. An example of this will be in C/C++. Heap is used for implementing dynamic allocation. In this case, memory can be freed, reused when not required.

The good thing about Python is that everything in Python is an object. This means that Dynamic Memory Allocation underlines Python Memory Management. When objects are no longer in use, the Python Memory Manager will automatically reclaim memory for them.


5.VALUE AND DEMAND

Python developers are high in demand not only because the language is so popular and widely used but mostly due to the fact that Python became a solution in many different areas. From web application, data science, web scrapping, etc.

Companies like Facebook, Google, Netflix, Amazon, Quora, etc uses Python.

However, its constantly growing especially in a start-up environment since it is user-friendly, scalable, robust, and innovative where time and budget are usually limited.


It is of course true that Python is not the only language. There are languages like JAVA, Pearl, C, C++ which also has its own merits. But if you are a start-up I will recommend you all to give it a try in PYTHON.
