What is Python?

Python is a popular programming language. Python is a high-level programming language it was created by Guido van Rossum in 1991 It was created by Guido van Rossum in 1991.
It is used for:
  • web development (server-side),
  • software development,
  • mathematics,
  • system scripting.

What can Python do?

  • Python can be used on a server to create a web application.
  • Python can be used alongside software to create the workflow.
  • Python can connect to the database system. It can also read and modify files.
  • Python can be used to handle big data and perform complex mathematically.
  • Python can be used for rapids prototyping, or for production-ready software development.

Why Python?

  • Python works on different platforms (Mac, Windows, Raspberry Pi, Linux, etc).
  • Python has a simple syntax something like the English language.
  • Python has syntax that allows the developer to write programs with fewer lines than some other programming languages.
  • Python runs on interpreter systems, meaning that code can be executed as soon as it is written. This means that prototyping can be very quickly.
  • Python can be treated in a procedural way, object-orientated ways or a functional way.

Good to know

  • a most recent major version of Python is Python 3, which we shall be using in this tutorial. However, Python 2, although not being updated with anything other than security updates,  still quite popular.
  • This tutorials, Python code will be written in a text editor. It is possible to write Python in an Integrated Development Environment, such as Thonny, Pycharm, Netbeans or Eclipse which are particularly useful when managing a larger collection of Python files.

Python Syntax compared to other programming languages

  • Python was designed readability and has some similarities to the English language with influence from mathematics.
  • Python uses a new line to complete a command, as opposed to other programming languages which often use semicolons or parentheses.
  • Python relies on an indentation, using whitespace, to define scope; such as the scope of loops, functions, and classes. Another programming language often uses curly-brackets for this purpose.
