Python is the interpreted, high-level, general-purpose programming language used in Web Development (as server-side language), ArtificialIntelligence, Image Processing, Machine Learning, Big Data, Scientific Computing, and several other fields. Top universities like CMU and MIT teach Python as the primary language in CS courses because of the simple syntax that makes it very easy for newbies to grasp and understand it easily. There are top 10 reasons to learn python as beginner or expert.
1. Dynamically Typed Language
Unlike other static-typed languages (Java, C, and C++), in which if we want to declare any type of variable, we first need to specify a type.
But, in python, we just put the name and assign it value and then python implicitly specify its type. In other words, Python does the Type Management.
We declare a variable in Java like this:
int i = 1; i = i / 2; (i now equals to 0, because it is integer value so it can't hold float value) In Python, we just need to declare the name of the variable: i = 1 i = i / 2 (i now equals to 0.5)
Python automatically changes the type of variables dynamically so that they can hold a value after any computation, like a float value in this situation.
2. Simple Syntax
Python has a very simple syntax for declaring variables, functions, blocks etc.
It uses the White Indentation to separate the statements. Unlike other programming languages, which use semicolons, colons, commas, braces, and brackets, which make the code more complex, and we spend more time in debugging because they cause several compile-time errors when not used properly or even not used at all.
3. English-Like Commands
Python is designed to be as much English-Like as possible. Dynamic-Type style makes python code more readable than most other static-typed programming languages.
In Java, we print name like this:
String name = "Lucy" (declaring string variable) System.out.println(name); In Python, we print name like this: name = "Lucy" (Python will automatically change this variable type to String) print(name) (Printing the name)
There are several things we can do in one line of code in Python, which will require 3 or more lines of code in other languages.
For Example: Swapping
In Java, it requires 3 lines of code:
int temp = x; x = y; y = temp; In Python, it requires 1 line of code: x, y = y, x
5. Used in Web Development
Python is used as a server-side programming language at large scale. Several top websites are developed in Python like YouTube, Instagram, Pinterest, Reddit etc. Python frameworks like Django and Flask make it easier to develop large web applications.
6. Used in Artificial Intelligence
Artificial intelligence is the future of the world. Python has gain popularity in most widely being used in AI and its sub-fields like Robotics, Image Processing for applying complex algorithms and computations. It definitely defines the fact that Python has a solid future in years to come.
7 - Used in Scientific Computing, Data Mining, and Machine Learning
Python has gained popularity in several computing fields like Scientific Computing, Data Mining, and Machine Learning.
8. Big Data
Big Data is data sets, which are too large and complex that traditional data processing application software programs are inadequate to deal with them. Python is also being used to solve problems and challenges of Big Data like Data Analysis, Data Mining and Data Storage etc.
9. Large Standard Library
Python's great strength is its large standard library and packages used in creating graphical user interfaces, networking, multimedia, databases, automation, web scraping, system administration, scientific computing, text processing and image processing etc.
10. Large Community
There are several open-source projects in Python we can find on Github.
And, there is a large community of Python programmers who help beginners and newbies in several situations on the forums like stackoverflow.com.
