[Tutor] getting iteration level

[David Bear]

Lets say I have a list object that I iterate over like this:

for item in myList:
   process(item)

During execution of the for loop something happens and I want to know how
many items have be iterated over, how do I find out? Without resorting to
some counter inside the loop, is there some python object I can ask?

Use enumerate(), it generates the list index for you:

for i, item in enumerate(myList):
   process(item)
   print 'processed item', i
