Exercise for reference:

Create a function that takes any string as input and returns the number of words for that string.

Answer:

def count_words(strng): 
    strng_list = strng.split() 
    return len(strng_list) 
 
print(count_words("Hey there it's me!"))

Explanation:

We're using split here which is a string method that splits a string into several strings given a separator passed inside the brackets. When you don't pass a separator, split will split a string at white spaces. This will output a list of strings..Applying len to that list returns the number of listitems, so the number of words.
