for loop is used to iterate over a sequence of items and perform a task on each item one after the other.

For loop on an array

x = [1,8,6,5]
for n in x:
	print('The number is {0}'.format(n))

# this will print
# The number is 1
# The number is 8
# The number is 6
# The number is 5

y = ['Nagasudhir', 'Lakshmi', 'Kishore']
for n in y:
	print('Hi {0}!'.format(n))
# this will print
# Hi Nagasudhir!
# Hi Lakshmi!
# Hi Kishore!

For loop on a sequence

In this example we are generating a sequence using range function

for n in range(1,10,2):
	print('The number is {0}'.format(n))

# this will print
# The number is 1
# The number is 3
# The number is 5
# The number is 7
# The number is 9
