#demo for loop, and while loop
phrase = raw_input("enter your phrase:")
VOWELS = "aeiou"
number = 0
for letter in phrase:
if letter.lower() in VOWELS:
number = number +1
else:
pass
You don't need the else if its only a pass statement.
print "Number of vowels =",number
raw_input("Press the enter key to continue.")
index = 0
while index < len(phrase):
if phrase[index] in VOWELS:
index = index +1
print "number of vowels" ,index
The index is the position in the string not the count of vowels.
But you are trying to use the same variable for both. Thats a bad idea.
Because you only increment the position if thre is a vowel you
get stuck if any letter is not a vowel. You need a new count variable
and keep index just for iterating in the loop..
