For Loop I
#!/usr/bin/python3
#
# Python program to demonstrate for loops.
#
# The for loop goes through a list, like foreach in
# some other languages. A useful construct.
for x in ['Bill', 'Alice', 'Joe', 'Sue' ]:
print(x, 'likes jelly beans.')
# The range operator simply creates a list of numbers
# in the indicated range. Note that the range ends
# before the second argument.
print(range(5, 10))
# Range works with for to create the traditional for loop.
for y in range(2, 10):
print(y,end=' ')
print()
for y in range(2, 10, 2):
print(y,end=' ')
print()
for y in range(20, 10, -1):
print(y,end=' ')
