Python Iterator

fruits = ["apples", "bananas", "cherries", "pears", "plums"]
fruitIterator = iter(fruits);
print(next(fruitIterator))
print(next(fruitIterator))
print(next(fruitIterator))

Python Iterating Through an Iterator

# 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__())

# Output: 3
print(my_iter.__next__())

# This will raise error, no items left
next(my_iter)

Iterating With for Loops in Python

names = ["Preet", "Ranjeet", "Adil"]
for name in names:
    print(name)
