Can anyone compare their answer with mine, Python?

I'm pretty sure that this wasn't the way that the teacher wanted us to solve this. There must be an easier way to get this right.

silly.py 
# The first half of the string, rounded with round(), should be lowercased.
# The second half should be uppercased.
import math

def sillycase(value):
  length = len(value)
  firsthalf = math.ceil(length/2)
  secondhalf = math.floor(length/2)

  if firsthalf > secondhalf:
    secondhalf = secondhalf+1

  firsttext = value[0:firsthalf]
  secondtext = value[secondhalf:]
  answer = firsttext.lower()+secondtext.upper()

  return answer


print(sillycase("frog")) #should return frOG
print(sillycase("trevor")) # treVOR
print(sillycase("kenneth")) # kennETH
print(sillycase("treehouse")) #treehOUSE

This should be a little more easy :)

def sillycase(my_str):
  half_lenght = round(len(my_str) / 2)
  return my_str[0:half_lenght].lower() + my_str[half_lenght::].upper()

What im doing is: Getting the rounded number of half the lenght of the string. Thats because slices use integers not floats. Returning my_str from index0 to half of the string + my_str from half of the string to the end of the string.

Hope this helped :-)

Hey Frederik,

Great answer.

Can you explain why int() would not also work in this case?

Hi meagantan,

Not sure if I get your question.

Are thinking of int(my_str)?

If you are, its because my_str contains letters. int() will only work if the string is numbers only.

For example:

int("123")

This will raise an ValueError:

int("abc")
int("a1b2c3")

Hope this helps :) If not just specify a bit more and il try to answer!
