Word_count question

I have gone thru this many times comparing correct answers but can someone explain to me what: dictionary[word] = string.lower().split().count(word)
is doing please. The = part is throwing me off.

def word_count(string): dictionary = {} for word in string.lower().split(): dictionary[word] = string.lower().split().count(word) return dictionary

wordcount.py 
def word_count(string):
    dictionary = {}
    for word in string.lower().split():
        dictionary[word] = string.lower().split().count(word)
    return dictionary

The key is the term in the brackets, in this case the contents of "word".

The value is what is being assigned, so it is whatever the expression on the right side of the equal sign evaluates to.
