Python is a broadly used general-purpose, excessive stage programming language. It was once at the start designed by Guido van Rossum in 1991 and developed by means of Python Software Foundation. It was once in the main developed for emphasis on code readability, and its syntax approves programmers to express principles in fewer lines of code.

Applications for Python

Python is used in many software domains. Here's a sampling.

Web and Internet Development

Python is used in many software domains.

Scientific and Numeric

Python is widely used in scientific and numeric computing:

Education

Python is a tremendous language for instructing programming, each at the introductory stage and in greater superior courses.

Software Development

Python is often used as a aid language for software program developers, for build control and management, testing, and in many other ways.

The average earnings of the python programmer

• The common Python developer income in the US is $110,021, in accordance to survey New York and California have the best Python developer profits - $122,135 and $121,443 accordingly.
• According to Indeed, the common Python programmer income is $123,743 per year.

Evolution of python programming language

Python

Python used to be brought via Guido Van Rossum in 1989.
In the early 1980s, Van Rossum used to work at CWI (Centrum voor Wiskunde en Informatica) as an implementer of the programming language called ABC. Later at CWI in the late 1980s, while working on a new disbursed running gadget referred to as AMOEBA, Van Rossum started searching for a scripting language with a syntax like ABC but with the get right of entry to to the Amoeba gadget calls. So Van Rossum himself began designing a new simple scripting language that should overcome the flaws of ABC

History of Python: Story at the back of the name

Python

Python grew during the early nineties, acquiring lambda, reduce(), filter() and map() practical programming tools (supposedly courtesy of a Lisp hacker who ignored them and hence submitted working patches), key word arguments, and built in guide for complex numbers.

Program to display multiplication desk by using using python. 

1.     # Multiplication table (from 1 to 10) in Python

2.     num = 12

3.     # To take input from the user

4.     # num = int(input("Display multiplication table of? ")

5.     # Iterate 10 times from i = 1 to 10

6.     for i in range(1, 11):

7.     print(num, 'x', i, '=', num*i)

Output

12 x 1 = 12
12 x 2 = 24
12 x 3 = 36
12 x 4 = 48
12 x 5 = 60
12 x 6 = 72
12 x 7 = 84
12 x 8 = 96
12 x 9 = 108
12 x 10 = 120

Source Code: Using a temporary variable

1. # Python program to swap two variable
2. x = 5
3. y = 10
4. # To take inputs from the user
5. #x = input('Enter value of x: ')
6. #y = input('Enter value of y: ')
7. # create a temporary variable and swap the values
8. temp = x
9. x = y
10. y = temp
11. print('The value of x after swapping: {}'.format(x))
12. print('The value of y after swapping: {}'.format(y))

Output

The value of x after swapping: 10
The value of y after swapping: 5

What is Python?

Before we pass to the organizations that use Python and think about strange cases why they do so, we must start from the very opening and learn some small print about what is Python language (if you don't want this basic information -- simply scroll down to the major topic).

What is Python desirable for?

Python

As it was once mentioned, Python was used for scripting and automation purposes. It nonetheless does, but there are some extra spheres the place the electricity of this language is invoked in. So, let's see what is Python used for today.
The benifits of the usage of python for game development
Most builders think of Python as a general-purpose programming language. For years, NASA, Google and even Instagram have used Python for facts evaluation and internet site development. However, this programming language has gone unused in the gaming industry until recently. There are many reasons why Python is gaining reputation with gaming developers and here are some of them. 

Difference Between Python and JavaScript?

Python is a deciphered elevated level programming language with dynamic semantics and article arranged programming intended to be anything but difficult to peruse and execute. It is a scripting language like Perl/ruby and utilized for making web applications as well. Java-Script is an item arranged programming language which enables you to make dynamic site pages and got institutionalized in ECMAScript language detail. Java-Script underpins diverse programming worldview as article situated, utilitarian, and basic programming however not procedural programming. 

Key Differences Between Python versus JavaScript 

• Python is specifically – no verifiable transformation between types though JavaScript is pitifully composed. 
• The synchronous and blocking code is standard in JavaScript while python as true as default. 
• JavaScript can be utilized to run on frontend while python is on server side programming or backend. 
Python has procedural programming while Java-Script doesn't have. 
• Java-Script has; as proclamation eliminator though python has a newline. 
• Python is a superior structured language which makes it simple to keep up though JavaScript is poor. 
• Python isn't useful for versatile advancement while Java-Script is great. 
• Python is delayed to run nearly to JavaScript. 
• Python gives immense standard library though JavaScript has a constrained standard library. 
• Python vigorously depends on task with no contrast among variable and task while JavaScript doesn't transfer. 
• Python has numerous libraries for logical registering, information investigation, and AI though JavaScript doesn't. 
• Python has support for some, numeral information types like int, glide, fixed-point decimal while Java-Script primarily deals with drifting point factors.
