Many of us stumble upon the same question, “as a beginner, should I learn Python 3?” If you are seeking the answer too, read this article, as I unravel what Python 3 has to offer. Programming using Python 3 has become the next-gen skill to acquire. No doubt, most entry level programmers are inclined towards completing Python Programming Certification. With rich features and vivid functionality to offer, Python 3 has taken the programming community by storm.
I have covered the following topics to help kick-start your journey to learn Python 3.
Python is a free open source, multi-purpose programming language, created by Guido Van Rossum in 1991. Since Python’s first release, the language has gone through many changes and improvements. It was built as a successor to programming language ABC. Python’s primary advantage was that it had the capability to handle exceptions and interface with an operating system named ‘Amoeba‘. With time Python language has evolved and grown manifolds. It’s time to study Python 3 language in detail.
Python has a range of advantages over other programming languages. I have covered a few important advantages of Python, below.
Python supports the re-usability and flexibility of programs. Python supports numerous modules, making easier to implement programs under domains like data analytics, machine learning, artificial intelligence, deep learning, etc.
When compared to other programming languages, Python is reliable and has rich support from its community. It’s interpreted nature adds to it being portable and time efficient.
Python follows clear structural specifications for writing its code, making it easy to read and edit. It redefines the cleanliness of code and doesn’t follow the traditional programming syntax.
According to recent surveys, it was concluded that Python is the most demanding programming language in the IT market. To start learning Python, you may consider reading more about the Python Institute’s PCAP certification and the career path to being a master in Python.
Now that we have spoken about Python 3 features, let us scoot towards a comparison between Python 3 and its predecessor Python 2.
After its release in 2008, Python 3 has evolved way more than its predecessor Python 2. Answering whether Python 3 being better than Python 2, is a no-brainer.
I have described the key differences between Python 3 and Python 2 below:
For example, look at the difference between the print function syntax for Python 2 and Python 3, as stated below.
print "Edureka Python Courseware"
print ("Edureka Python Courseware")
The latest release of Python is Python 3.6.1. Few key features from the latest release are given below:
We’ve studied the differences that Python has with its predecessor. Now, it’s time to talk about the competitors of Python 3.
It is easy and efficient to read Python code. Python also comes bundled with a single line HTTP server setup capability. Whereas Java is complex and it has higher compile time and memory usage.
Python 3 is faster in the execution of shorter codes. R is a programming language that supports the statistical analysis and data mining. Hence it is a field-specific language. R has limitations when it comes to developing web applications.
Python 3 has wide support of packages that allow applicability across different platforms. Go lang has its applications more inclined towards system programming, cloud computing, and web development. Henceforth Go Lang has field-specific applicability.
Having said that, let me shed some light on the valuable features of Python 3 in detail.
Python 3 offers rich functionality making it the most appropriate for solving real-life problems. I have written down a few important features of Python, below:
Let us understand each of these features in detail.
Python is an open source language and is free for use. Download the Python environment from the Python global webpage – http://www.python.org.
Python is portable and can be executed on any platform. Python 3 stores code as a byte code before it is interpreted on a platform.
Python code doesn’t need to be compiled. It is interpreted on the machine, it has been executed on.
Python has features of an object-oriented as well as a procedural programming language. It supports the usability of functions, classes, and objects. An object-oriented approach strengthens the diverse application of Python in various fields.
Python is fast to execute and run. It is efficient to develop and maintain scripts in Python. Python’s code is easy to read and it’s indentation approach keeps the code clean.
Few of Python’s packages have been described below:
Used to facilitate array handling and complex matrix functions
Used for real-time digital image processing
Used for data analysis
Used for visualization of data
Used to develop applications using Machine learning
Used to build GUI applications
Python has numerous array of applications. Let’s have a look at the applications that you can build with Python 3.
Few of the most important domains in which Python is used to develop applications is described below:
A bunch of applications that run on Python 3 code is present in the picture below:
With this perennial reach of Python, it is natural to ask, where should one begin learning Python 3 from? To answer that question, I have represented a fundamental learning path for learning Python 3 in the section below:
I have written down the fundamental topics that you should study in order to get started with Python 3.
Variables are used to store information in memory. It can then be invoked later to perform calculations.
Loops and conditional statements are used to control the flow of a program. A few examples are, while loop, for loop, Switch statement, etc.
File I/O operations are ways to fetch information from one source and send it out to a different target.
Exception handling is a functionality that allows us to identify errors and debug programs.
Reusable and interactive GUI applications can be built using libraries of Python 3.
Python’s libraries can be used to create REST APIs and responsive WebUI applications.
Python’s code should be tested to meet the business requirement and functional test jobs can be integrated with Selenium for automated testing.
Awesome! You have now learned the fundamentals of Python. Let’s write a simple code and get familiar with scripting in Python.
I have written a Python 3 code to find whether the number entered is Prime. This example will make you a little familiar with the syntax that a Python 3 program follows.
Property of prime number – Every number that is only divisible by 1 and itself, is a prime number. Note the exclusivity of division by 1 and the number itself.
Count = 0 # Count used as a iterating variable numprime = int(input("Enter the number which needs to be checked for being Prime or not : ")) for i in range(1, numprime): if numprime % i == 0: # Checks if the number is divisible by numbers Count+=1 # increments the counter ++i # increments the loop variable if Count > 1: # Checks if the number of divisible events are more than 1 print("Darn, the number", numprime, "is not a Prime number") else: print("Voila! the number", numprime, "is a Prime number")
Congratulations! Your first Python 3 program executes without errors. The output of the program is given below:
I hope you were able to read through the article and get a fair understanding to learn Python 3 programming. Python 3 is like a Swiss knife of functionalities, that a programming language can execute. As a result, get inspired and learn Python 3 today!
