Why won't my sillycase work?

It seems fine to me, weird....

sillycase.py 
def sillycase(string):
    len(string) = string_length
    int(string_length / 2) = string_middle
    list(string)
    first_half = string[:string_middle]
    first = str.lower(''.join(first_half))
    second_half = string[string_middle:]
    second = str.upper(''.join(second_half))
    new = first+second
    return new

Hiya Marie! First off, You cant do len(string) = string_length, coz in programming , you're assigning a value to right sided of assignment operator. Secondly, i cant read your code it all. Remember you need to make your code readable for other programmers as well. But i did pick this up that you're not doing "integer division", which denoted as "//". Integer division not only does a division for ya, it rounds the value as well. So this is how your code should look like:

def sillycase(words):
    halves = len(words)//2
    return words[:halves].lower() + words[halves:].upper()

By making it readable do you mean adding comments or just simplifying overall? I think the simplifying might take me some time as I start working on projects I'll start figuring out what I'm doing unnecessary (hope I'm right in that logic :) )

When i say readable, i mean refactoring your code and following guidelines to write elegant and readable for human sets of eyes. Writing clean and elegant codes is itself an art. I mean yeah i wont expect any beginners to master right away but you can always practice. And compare your code with mine, you code took like 12 lines and mine took 3. So try to reduce the amount of lines.

This is an excellent guide to write elegant ad sexy codes.
