Python

Python is a high-level, interpreted, interactive and object-oriented scripting language. Python is designed to be very readable.
It uses English keywords frequently whereas other languages use punctuation.
It has fewer syntactical constructs than other languages and it makes use of indentation to mark the beginning and end of program blocks which can sometimes be less obvious to a beginner.

Here are some tips for getting started with Python:

  • A Python identifier is a name used to identify a variable, function, class, module or other object.
  • Identifiers start with an alphabetic letter (upper or lowercase) or an underscore (_) followed by zero or more letters, underscores and digits (0 to 9).
  • Python does not allow punctuation characters such as @, $, and % within identifiers.
  • Python is a case sensitive programming language.
    For example VarName and varname are two different identifiers.
