Get loop count inside a Python FOR loop

Question

In a Python for loop that iterates over a list we can write   for item in list      print item   and it neatly goes through all the elements in the list  Is there a way to know within the loop how many times I ve been looping so far  For instance  I want to take a list and after I ve processed ten elements I want to do something with them   The alternatives I thought about would be something like   count 0 for item in list      print item     count   1     if count   10    0          print  did ten    Or   for count in range 0 len list        print list count      if count   10    0          print  did ten    Is there a better way  just like the for item in list  to get the number of iterations so far
