What is Python?
Python is a multipurpose programming language that is used for a wide variety of applications. It includes high-level data structures, dynamic typing, dynamic binding and many more features that make it as useful for complex application development. Python is an interpreted, interactive, object-oriented programming language. It incorporates modules, exceptions, dynamic typing, very high level dynamic data types, and classes. Developed in the late 1980s and early 90s by Guido van Rossum, Python has advanced as an open source programming language.
Who is a Python Developer?
Python developers are programmers who specialize in writing scalable server-side web application logic and functions using Python language. They develop, debug, test and implement application projects in Python. They also connect applications with third-party web services and support front-end developers with application integration.
Average salary of Python developers
Average salary of Python developers varies according to their programming experience in different countries. In United States, average wage of Python programmer is 50K to 90K US$. In UK & Europe, its around 45K US$ to 75K US$. In India, it varies between 8 lacs INR to 28 Lacs INR and in other south asian countries, its little lower than this.

Benefits of hiring dedicated Python developers
Python programming language boasts of great efficiency and readability. Python language delivers more in less for example, other programming languages such as Java, may require as many as three lines of code to print a line, while Python can do the same in a single line of code. Python highly readable codes make it easier for developers to understand the program and debug it even if they are not the original developers. More over, Python developers are capable of building minimum viable products, or MVPs, that can act as prototypes of the actual product in the shortest time to make go-to-market as low as possible.
