# Program Description
#   Calculates the average word length in a sentence
#   entered by the user
#
# Algorithm (pseudocode)
#   Print intro
#   Get sentence from user
#   Split sentence into words
#   Accumulate total length of words
#   Divide by number of words to get average word length
#   Print results

    print('This program calculates the average word length in a sentence entered by the user.')

    # Get sentence from user
    inputStr = input('Please enter a sentence: ')

    # Split sentence into words
    words = inputStr.split(' ')

    # Accumulate total length of words
    ttlLen = 0
    for word in words:
        ttlLen += len(word)

    # Divide by number of words to get average word length
        avgWrdLen = ttlLen / len(words)

    # Print results
    print('    Number of words: {0}\nAverage word length: {1:.1f}'.format(len(words), avgWrdLen))
