Hi Vedang! The question is simple. We have to create a function named stringcases which takes a string as a argument and returns a tuple with following String in:

  1. uppercase format. 2.lowercase format. 3.Titlecase format(only first letter capital) 4.And reversed.

The execution is simple:

def stringcases(st):
    my_list = list(st)
    string_reversed = my_list[-1::-1]
    my_tuple = st.upper(),st.lower(),st.title(), ''.join(string_reversed)
    return my_tuple

for reversing the string, we first create a list with letters of the string, and then reverse it using Slices, and then join the letters together using ''.join(my_list) function. We put all this into a tuple and return the tuple.

Hope you understand this, if not feel free to ask anytime!

My_list = list(st) Here we are creating a list by iterating a string.

Eg: my_list = list("Hello") Will be my_list= ['H','e','l','l','o']
