Iterators.py

# Iterators are objects that represent a stream of data. It returns
# the data in the stream one at a time.
# Any object that supports iteration is called an iterable

# For loops creat iterators for you.
# The code block below prints out each character before terminating
# string = "1234567890"

# for char in string:
    # print(char)
# The code block below shows the iterator in action, using the next
# function to go through each iterator
# my_iterator = iter(string)
# print(my_iterator)
# print(next(my_iterator))
# print(next(my_iterator))

#     for item in list1:
#         print(next(new_iter))
