2.13. for Loop and the range() Built-in Function

The for loop in Python is more like a foreach iterative-type loop in a shell scripting language than a traditional for conditional loop that works like a counter. Python's for loop takes what we will later describe as a sequence type (list, tuple, or string) and iterates over each element of that sequence.

>>> print 'I like to use the Internet for:'

>>> for item in ['e-mail', 'net-surfing', 'homework', 'chat']:
…       print item
…
