# Iteration is the execution of a statement repeatedly and without
# making any errors.iterator in python
# define a list
my_list = [4, 7, 0, 3]
# get an iterator using iter()
my_iter = iter(my_list)
# iterate through it using next()
# Output: 4
print(next(my_iter))
# Output: 7
print(next(my_iter))
# next(obj) is same as obj.__next__()
# Output: 0
print(my_iter.__next__())

<loop body>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)python iterator
pies = ["cherry", "apple", "pumpkin", "pecan"]
iterator = iter(pies)
print(next(iterator))
#prints "cherry" because it's the current one being iterated overCopyright © 2021 Codeinu
