Python: iterators

Iterators: Is a way to access elements within a collection iterator creation and access:

>>> list = [1,2,3,4]>>> it = iter (list)   # iterator creation >>> next (IT)   # access iterators, accessible only through next (), cannot be accessed by index 1>>> next (it) 2>>> Next (IT) 3>>> Next (it) 4>>> Next (IT)   Traceback (most recent call last):   " <pyshell#37> "  in <module>    next (IT) stopiteration

Iterator traversal:

list=[1,2,3,4#  Creating an Iterator object  for in it:        Print (x, end= " ")

Output Result:

1 2 3 4
