Python is a very simple language, and has a very straightforward syntax. It encourages programmers to program without boilerplate prepared code.
The simplest directive in Python is the "print" directive - it simply prints out a line and also includes a newline, unlike in C. There are two major Python versions, Python 2 and Python 3. Python 2 and 3 are quite different. This tutorial uses Python 3, because it more semantically correct and supports newer features.
For example, one difference between Python 2 and 3 is the print statement.
In Python 2, the "print" statement is not a function, and therefore it is invoked without parentheses. However, in Python 3, it is a function, and must be invoked with parentheses.
To print a string in Python 3, just write: Both tabs and spaces are supported, but the standard indentation requires standard Python code to use four spaces.
