• Python


  A popular programming language created by Guido van Rossum and released in 1991
• What Python is used for

  • Web development (server-side)
  • Software development
  • Mathematics
  • System scripting
• What Python can do

  • Create web applications on a server
  • Create workflows alongside software
  • Connect to database systems and read/modify files
  • Handle big data and perform complex mathematics
  • Rapid prototyping or production-ready software development
• Why Python


  • Works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc)
  • Has a simple syntax similar to the English language
  • Has syntax that allows developers to write programs with fewer lines than some other programming languages
  • Runs on an interpreter system, allowing for quick prototyping
  • Can be treated in a procedural, object-oriented or functional way
• Python can be written in

  A text editor or an Integrated Development Environment (IDE) such as Thonny, Pycharm, Netbeans or Eclipse
• Python syntax compared to other programming languages

  • Designed for readability, with similarities to English and mathematics
  • Uses new lines to complete a command, rather than semicolons or parentheses
  • Relies on indentation using whitespace to define scope, rather than curly-brackets
• Python Operators


  • Arithmetic operators
  • Assignment operators
  • Comparison operators
  • Logical operators
  • Identity operators
  • Membership operators
  • Bitwise operators
• Arithmetic operators


  Used with numeric values to perform common mathematical operations
• Assignment operators
