Python - Iterator

Python Iterator

---------------------

An iterator is an object that contains a countable number of values.

An iterator is an object that can be iterated upon, meaning that you can traverse through all the values.

Iterator Methods:

---------------------

1. iter()  - used to get an iterator

2. next()- next() function to manually iterate through all the items of an iterator

~~~~~~~~~~~~~~~~~~~~~~~~

#Program 1 : Example program for iterator

a=[10,20,5,7,90]

i=iter(a)

print(next(i))

print(next(i))

print(i.__next__())

print(i.__next__())

print(i.__next__())

print(next(i))

~~~~~~~~~~~~~~~~~~~~~~~~

#Program 2 : Example program for iterator

mytuple = ("apple", "banana", "cherry")

myit = iter(mytuple)

print(next(myit))

print(next(myit))

print(next(myit))

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

#Program 3 : Example program for iterator

mystr = "jahab"

myit = iter(mystr)

print(next(myit))

print(next(myit))

print(next(myit))

print(next(myit))

print(next(myit))
