Hi, here is my solution to the challenge.

def word_count(string):  #here we define the function word_count which takes 1 argument, a string
  dictionary = {}        #in this line we create an empty dictionary where the words and count will be stored
  a = string.split()     #here, the string is split into all of the individual words and stored in the variable a
  for i in a:            #for each word in the variable/ list a
    if i in dictionary:  #if it is in the dictionary
      dictionary[i] += 1 #add one to the word count
    else:                #however if it is not in the dictionary
      dictionary[i] = 1  #add it to the dictionary and set the word count to 1

  return dictionary      #finally, we return the dictionary

I hope my explanation was clear enough and that you understand now!
