Hello,
I'm doing this challenge and I don't have a clue how to change the case of a letter using the round() function it suggests. I've tried to use dir(round) to see if that helps and also using the online documentation but no luck. i though 'round(text[0:4])' would round the first 5 digits but it doesn't

The general idea here is that we wanna divide the length of the String argument by 2, then use that number to slice the String into half, upcase the first half, downcase the 2nd half, then combine them back together, that's the return result of the function.
However, the length of the String can be odd number, divide an odd number by 2 will result in floating point number, and it's illegal to slice String using floating point. That's why you need to use round()
method to round the division result to an integer.
round(len(String) / 2)
that's how you use the round()
method here, I'll leave it to you to figure out the rest. Feel free to ask if you have more questions.
