What is Python?

Python is a popular programming language. It was created by Guido van Rossum, and released in 1991.Python is a dynamic, interpreted (bytecode-compiled) language. There are no type declarations of variables, parameters, functions, or methods in source code. This makes the code short and flexible, and you lose the compile-time type checking of the source code. Python tracks the types of all values at runtime and flags code that does not make sense as it runs.

Use for:

  • web development (server-side),
  • software development,
  • mathematics,
  • system scripting.

Why we choose Python?

  1. Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc).
  2. Python has a simple syntax similar to the English language.
  3. Python has syntax that allows developers to write programs with fewer lines than some other programming languages.
  4. Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick.
  5. Python can be treated in a procedural way, an object-oriented way or a functional way.
  6. Python Syntax compared to other programming languages
  7. Python was designed for readability, and has some similarities to the English language with influence from mathematics.
  8. Python uses new lines to complete a command, as opposed to other programming languages which often use semicolons or parentheses.
  9. Python relies on indentation, using whitespace, to define scope; such as the scope of loops, functions and classes. Other programming languages often use curly-brackets for this purpose.

Python Extension:

Python source files use the ".py" extension and are called "modules." With a Python module hello.py, the easiest way to run it is with the shell command "python hello.py Alice" which calls the Python interpreter to execute the code in hello.py, passing it the command line argument "Alice". See the official docs page on all the different options you have when running Python from the command-line.

Finding an Interpreter:

Windows:

There are many interpreters available freely to run Python scripts like IDLE (Integrated Development Environment) that comes bundled with the Python software downloaded from http://python.org/. 


Linux:

Python comes preinstalled with popular Linux distros such as Ubuntu and Fedora. To check which version of Python you’re running, type “python” in the terminal emulator. The interpreter should start and print the version number.




macOS: 

Generally, Python 2.7 comes bundled with macOS. You’ll have to manually install Python 3 from http://python.org/.


Industrial Importance of Python:

Most of the companies are now looking for candidates who know about Python Programming. Those having the knowledge of python may have more chances of impressing the interviewing panel. So I would suggest that beginners should start learning python and excel in it.

Python is a high-level, interpreted, and general-purpose dynamic programming language that focuses on code readability. It has fewer steps when compared to Java and C. It was founded in 1991 by developer Guido Van Rossum. Python ranks among the most popular and fastest-growing languages in the world. Python is a powerful, flexible, and easy-to-use language. In addition, the community is very active there. It is used in many organizations as it supports multiple programming paradigms. It also performs automatic memory management.

Advantages: 

  • Presence of third-party modules 
  • Extensive support libraries (NumPy for numerical calculations, Pandas for data analytics etc.) 
  • Open source and community development 
  • Versatile, Easy to read, learn and write
  • User-friendly data structures 
  • High-level language 
  • Dynamically typed language(No need to mention data type based on the value assigned, it takes data type) 
  • Object-oriented language 
  • Portable and Interactive
  • Ideal for prototypes – provide more functionality with less coding
  • Highly Efficient(Python’s clean object-oriented design provides enhanced process control, and the language is equipped with excellent text processing and integration capabilities, as well as its own unit testing framework, which makes it more efficient.)
  • (IoT)Internet of Things Opportunities
  • Interpreted Language
  • Portable across Operating systems
