8.5. for Statement

The other looping mechanism in Python comes to us in the form of the for statement. Unlike the traditional conditional looping for statement found in mainstream third-generation languages (3GLs) like C, Fortran, or Pascal, Python's for is more akin to a scripting language's iterative foreach loop.

8.5.1. General Syntax

Iterative loops index through individual elements of a set and terminate when all the items are exhausted. Python's for statement iterates only through sequences, as indicated in the general syntax here:

							for
							iter_var in sequence:
							suite_to_repeat
						

The sequence sequence will be iterated over, and with each loop, the iter_var iteration variable is set to the current element of the sequence, presumably for use ...
