half of indexes

I know that one of the first steps is is to separate the indexes of whatever string is inputted into two halfs using indexes, but I can't think of a way to do this.

Hi Andrew! You'll need to use len() to get the length of the string, and create a variable for that number // 2. You can use variable names when indexing an item, as long as that variable represents an integer. So, use that variable that is half of the length of whatever the string is and use it to lowercase and uppercase the string! Example of what I mean:

def half_of_the_string(string):
    num = len(string) // 2
    # // is the operand that returns a whole integer even when dividing an odd number by 2
    print(num)

half_of_the_string('apples')
3
half_of_the_string('Treehouse')
4
half_of_the_string('abcdefghijklmnopqrstuvwxyz')
13

With this knowledge, return the concatenation (+) of the first half of the string, lowercased, and the second half of the string, capitalized. Hope this helps, and happy coding!
