Python Python Collections (2016, retired 2019) Slices sillyCase

Is there a different approach to solving this challenge?

def sillycase(string): string1 = sillycase[:len(string)//2].lower() string2 = sillycase[len(string)//2:].upper() return string1 + string2

sillycase.py
def sillycase(string):
    string1 = sillycase[:len(string)//2].lower()
    string2 = sillycase[len(string)//2:].upper()
    return string1 + string2

Sorry, I meant the following code:

def sillycase(string):
    string1 = string[:len(string)//2].lower()
    string2 = string[len(string)//2:].upper()
    return string1 + string2

You seem to have the "classic" solution there. You could eliminate the temporary string variables and add one to prevent calculating the size twice, but that's just minor implementation differences, not really a change in approach:

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

Thanks Steven!
