python - Python：在打印合并排序功能的结果时，print选项提供所有步骤。 如何只打印最终排序的数组？(Python: While printing the result of merge sort function, print option gives all steps. How to print only final sorted array?)

Question

Here is the code for the function which must return new sorted list, how do I get only the final arr printed, since it prints all steps?

(这是该函数的代码，该函数必须返回新的排序列表，我如何只打印最终的arr，因为它会打印所有步骤？)

def mergeSort(list_to_sort, ascend=True): arr=list_to_sort

(def mergeSort（list_to_sort，ascend = True）：arr = list_to_sort)

if len(arr) > 1:
    mid = len(arr) // 2
    left = arr[:mid]
    right = arr[mid:]

    # Recursive call on each half
    mergeSort(left)
    mergeSort(right)

    # Two iterators for traversing the two halves
    i = 0
    j = 0

    # Iterator for the main list
    k = 0

    while i < len(left) and j < len(right):
        if left[i] < right[j]:
            # The value from the left half has been used
            arr[k] = left[i]
            # Move the iterator forward
            i += 1
        else:
            arr[k] = right[j]
            j += 1
        # Move to the next slot
        k += 1

    # For all the remaining values
    while i < len(left):
        arr[k] = left[i]
        i += 1
        k += 1

    while j < len(right):
        arr[k] = right[j]
        j += 1
        k += 1

    if ascend:
        pass
    else:
        arr = arr[::-1]

print(arr)

mergeSort([54, 26, 93, 17, 77, 31, 44, 55, 20],False)

(mergeSort（[54，26，93，17，77，31，44，55，20]，假）)
