example of python iterators

Example 1: what is iterator in python

An iterator is an object that can be iterated upon, meaning that you can traverse through all the values.
#EXAMPLE OF ITERATOR
nums=[2,3,4,5,6,7]
it=iter(nums)
print(it.__next__())
for i in it:
  print(i)

Example 2: python iterator

pies = ["cherry", "apple", "pumpkin", "pecan"]

iterator = iter(pies)

print(next(iterator))
#prints "cherry" because it's the current one being iterated over
