iterables python code example

Example 1: what does iterable mean

#An iterable is any Python object capable of returning its members one at a time, permitting it to be iterated over in a for-loop. Familiar examples of iterables include lists, tuples, and strings - any such sequence can be iterated over in a for-loop.

Example 2: how to use iteration in python

for i = 1 to 10
    <loop body>

Example 3: python iterator

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

iterator = iter(pies)

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

Example 4: how to use iteration in python

n = 5
while n > 0:
    print n
    n = n-1
print 'Blastoff!'
