#now let's make things a little more challenging.
#
#last exercise, you wrote a function called word_count that
#counted the number of words in a string essentially by
#counting the spaces. however, if there were multiple spaces
#in a row, it would incorrectly add additional words. for
#example, it would have counted the string "hi david" as
#4 words instead of 2 because there are two additional
#spaces.
#
#revise your word_count method so that if it encounters
#multiple consecutive spaces, it does *not* count an
#additional word. for example, these three strings should
#all be counted as having two words:
#
# "hi david"
# "hi david"
# "hi david"
#
#other than ignoring consecutive spaces, the directions are
#the same: write a function called word_count that returns an
#integer representing the number of words in the string, or
#return "not a string" if the input isn't a string. you may
#assume that if the input is a string, it starts with a
#letter word instead of a space.
#write your function here!
#below are some lines of code that will test your function.
#you can change the value of the variable(s) to test your
#function with different inputs.
#
#if your function works correctly, this will originally
#print:
#word count: 4
#word count: 2
#word count: not a string
#word count: not a string
#word count: not a string
print("word count: ", word_count("four words are here! "))
print("word count: ", word_count("hi david"))
print("word count: ", word_count(5))
print("word count: ", word_count(5.1))
print("word count: ", word_count(true))
