(In C/C++/C#/Java, you need to declare the name and type of a variable before using it.) Python associates types with the objects, not the variables, i.e., a variable can hold object of any types. A variables is created via the initial assignment. You do NOT need to declare variables (name and type) before using them.
Variable Type Declaration: Like most of the scripting interpreted languages (such as JavaScript/Perl), Python is dynamically typed.(C/C++/C#/Java use double quotes for string and single quotes for character. Python also supports multi-line string, delimited by either triple-single ( '''.''') or triple-double quotes ( """."""). String: Python's string can be delimited by either single quotes ( '.') or double quotes ( ".").(C/C++/C#/Java end-of-line comment begins with '\\'. Python does not support multi-line comments. Comment: Python's comment begins with a '#' and lasts until the end-of-line.
This section is for experienced programmers to look at Python's syntaxes and those who need to refresh their memory. I personally recommend that you learn a traditional general-purpose programming language (such as C/C++/Java) before learning scripting language like Python/JavaScript/Perl/PHP because they are less structure than the traditional languages with many fancy features. This article is NOT meant to be an introduction to programming. I shall assume that you are familiar with some programming languages such as C/C++/Java.
