如何按字母顺序对地图数组进行排序

def quicksort(arr):
    if len(arr) <= 1:
        return arr
    pivot = arr[len(arr) // 2]
    left = [x for x in arr if x < pivot]
    middle = [x for x in arr if x == pivot]
    right = [x for x in arr if x > pivot]
    return quicksort(left) + middle + quicksort(right)

map_array = ['C', 'A', 'B', 'D', 'F', 'E']
sorted_array = quicksort(map_array)
print(sorted_array)
