''' Purpose: determine the length and number of vowels of a user-specified word
'''

# HELPFUL CONSTANT

VOWELS = 'aeiou'

# get the input
reply = input( 'Enter a word: ' )

# clean it up
word = reply.strip() #<--- removes leading and trailing whitespace
# how will we check the actual letters without caring about upper/lowercase?
word = word.lower() # Now the word is in lowercase and we can ignore uppercase (in case the user gives us weird input)
# ^ This is called canonical form

# determine and report its length
n = len( word )
print( "length:", n )

# determine and report the total of the number of occurrences of each of the vowels
total_vowels = 0
for vowel in VOWELS: # for each character in the string VOWELS. vowel becomes each character on each loop
    #print( vowel )
    # determine the number of occurrences of vowel in word
    occurrences_of_vowel = word.count(vowel)
    # print( vowel, occurrences_of_vowel )
    # print statements in loops is good for debugging (take them out before you submit)
    # add the number of occurrences to the total
    total_vowels = total_vowels + occurrences_of_vowel #<-- this is called accumulation.
#     Since we're counting a total, our accumulator (total_vowels) starts at 0

print( "vowels:", total_vowels )
