Python Python Collections (2016, retired 2019) Tuples Stringcases

Posted by Idris Abdulwahab

Collections (tuples)

The quiz challenge is: Create a function named stringcases that takes a single string but returns a tuple of different string formats. The formats should be: All uppercase All lowercase Titlecased (first letter of each word is capitalized) Reversed There are str methods for all but the last one.

My function, when tried, in workspaces returns a tuple with the different string formats but I'm still not getting through with the quiz challenge.

Please help.

Thank you.

stringcases.py 
def stringcases(str):
    wow = str[-1::-1]
    print ("{}" "," "{}" "," "{}" "," "{}".format((str.upper()), (str.lower()), (str.title()), (wow)))

Hello Idris! So the question is asking you to return a tuple. Your code, unfortunately, is printing the values, not adding them to a tuple. You can try something like this:

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

When you return values separated by a comma, you will ultimately return a tuple containing those values. Hope that helps!

JD Villa, thank you for that quick hint. I sometimes get confused with requirements of the questions. I thought I was required to use the format keyword in returning the values. I was almost there but I obviously lost my way. Thank you for your help on this. Cheers.
