#for loop
for letter in 'python':
    print 'current letter:',letter

#creat a list of five colors
colors=['red','blue ','green','yellow','orange']
print colors

for green in 'favorite colors':
   print 'favorite colors:',colors

#range
for a in range(20):
    print(a)

#using xrange
for x in xrange(20):
    print x

#using odd number in xrange
for x in xrange(30):
    if x%2==0:
        continue
print x

#using even number in xrange
for w in xrange(20):
    if w%2!=0:
        continue
    print w

#counting from 500,600
for x in xrange(500,600):
    print x

#working with while loop
count=0  
while(count<9):
    print 'the count is:', count
    count=count+1

#using while loop
add=11
while(add<35):
    print 'this is great then :',add
    add=add+1
