Python Python Collections (2016, retired 2019) Slices sillyCase

What is wrong with this python code? I've tried it on my IDLE and it works fine....

^^^

sillycase.py
def sillycase(a):
    x = len(a) / 2
    x = int(x)
    y = a.upper()
    z = y[:]
    z = z.lower()
    y = list(y)
    y[0:x] = z[0:x]
    y = str(y)
    return y

The object of this exercise if I remember rightly is to return the given string argument in partial upper and lower case. Your code returns a list of characters.

You need to join the string. To do this modify the second last line of code to:

y = ''.join(y)

and you should get the result you need.

My own code looked like this:

def sillycase(x):
    lengte = (int(len(x)))
    lengte_divided = (int(lengte / 2))
    mod_str_1 = x[:lengte_divided].lower()
    mod_str_2 = x[lengte_divided:].upper()
    return(mod_str_1 + mod_str_2)

Both should pass the challenge.

Hope this helps.

You don't have to make them lists, try making two strings and adding(+) them together

slices are also usable on strings

Thank you for the help! Now it works perfectly.
