This tutorial will explore how to solve the problem of sorting characters in a Python string in alphabetical order. We’ll learn about manipulating strings in Python and discuss how to compare various sorting algorithms. Finally, we’ll put the pieces together to create a solution using the merge sort algorithm. Problem-solving can be quite challenging, but with the right approach, we can find an efficient solution with minimal time and space complexity.

A student was trying to create a function that sorts all the letters of a word in Python, but their code was broken. The code had several errors, including using the wrong method to convert the word into a list of letters and trying to sort the output of a function that doesn’t have a sort method. The task was to fix the errors and make the function work. As an added challenge, the goal was to shrink the fixed code into a single line. The correct code uses the list() function to convert the word into a list of letters, uses the sort() method on the list, and then converts the list back into a string using the join() method.
