I was playing in the REPL with this function and can't figure out why word2 returns an empty string after join method?
Basically as I stated. In the REPL word1 joins into 'str' just like i was hoping, but word2 returns "". If it's the same logic what is causing this?
def sillycase(string): string = list(string) half = int(len(string)) // 2 word1 = string[:half] word1 = "".join(word1[:half]).lower() word2 = string[half:] word2 = "".join(word2[half:]).upper() return word1 + word2

You don't need the join, but what's happening here would be the same with or without it.
When "word2" is first assigned, it gets "half" of the iterable: "
word2 = string[half:]"
Then, on the next line, the "join" starts with taking another slice: "
But if the first slice made it only "half" long, then another slice that has a start value of "half" would not have any content.

I don't kwow why you should use "join". You can do this:
def sillycase(string): half = int(len(string)) // 2 word1 = string[:half].lower() word2 = string[half:].upper() return word1 + word2
