如何在python中显示冒泡排序中的比较以及交换数量

def bubble_sort(arr):
    n = len(arr)
    comparisons = 0
    swaps = 0
    for i in range(n):
        for j in range(0, n-i-1):
            comparisons += 1
            if arr[j] > arr[j+1]:
                swaps += 1
                arr[j], arr[j+1] = arr[j+1], arr[j]
    
    print("比较次数：", comparisons)
    print("交换次数：", swaps)
    return arr

# 示例用法
arr = [64, 34, 25, 12, 22, 11, 90]
sorted_arr = bubble_sort(arr)
print("排序结果：", sorted_arr)
