When I check my work, I get the error "Bummer! Where's 'stringcases()'?"
I have stringcases(word) defined and that error goes away when I remove 'word' from my definition, but there is no way to have a function act on an argument if it doesn't accept arguments. Is there something I'm missing here?
This code works as expected when tested in the workspace, so I'm at a loss as to what I need to be doing differently. Is there a chance there's a mistake in the challenge?
# Handy functions:
# .upper() - uppercases a string
# .lower() - lowercases a string
# .title() - titlecases a string
# There is no function to reverse a string.
# Maybe you can do it with a slice?
def stringcases(word):
up = word.upper()
low = word.lower()
titl = word.title()
rev = word[::-1]
return(up, low, title, rev)

def stringcases(word):
up = word.upper()
low = word.lower()
titl = word.title() #<-- Typo "titl" instead of "title"
rev = word[::-1]
return(up, low, title, rev) #<-- "title" not defined due to typo
With "title" undefined, the function doesn't load, therefore is not found.

def stringcases(data):
return(data.upper(),data.lower(),data.title(),data[::-1])

To check the efficiency, I ran both the corrected OP solution and your solution 5 times in loops of 1,000,000 executions each. Time is in seconds:

So unless you're running this code a lot, the difference is negligible
