Here's the corrected code: ``` def quicksort(my_list, first_index, last_index): if first_index < last_index: # Call the partition() function with the appropriate parameters partition_index = partition(my_list, first_index, last_index) # Call quicksort() on the elements to the left of the partition quicksort(my_list, first_index, partition_index - 1) quicksort(my_list, partition_index + 1, last_index) my_list = [6, 2, 9, 7] quicksort(my_list, 0, len(my_list) - 1) print(my_list) ``` The code defines a quicksort function that sorts a list using the quicksort algorithm. It takes three parameters: my_list, which is
