定时器内部功能

Question

编辑：我需要一个计时器，用于计算用户输入无序列表后需要花费多长时间。

我似乎无法运行time_selection_sort函数。我希望计时器在用户输入列表后立即开始。

from time import perf_counter
def swap(lst, i, j):
tmp = lst[i]
lst[i] = lst[j]
lst[j] = tmp

def swap_if_greater(lst, i, j):
if lst[i] > lst[j]:
    tmp = lst[i]
    lst[i] = lst[j]
    lst[j] = tmp

def find_index_of_min(lst):
min_index = 0
min_value = lst[0]
for i, value in enumerate(lst):
    if value < min_value:
        min_index = i
        min_value = value
return min_index
def selection_sort_out_of_place(input_list):
    # make a copy so we don't destroy the original data
    input_list = list(input_list)
    output_list = []
    # sort values into output_list, one at a time
    while input_list:
        print('Input list:', repr(input_list))
        print('Output list:', repr(output_list))
        min_index = find_index_of_min(input_list)
        value = input_list.pop(min_index)
        print('Sorting the value', repr(value))
        output_list.append(value)

    return output_list

def time_selection_sort(input_list):
    # generate random list
    lst = selection_sort_out_of_place(input_list)
    # measure running time
    start_time = perf_counter()
    insertion_sort(lst)
    end_time = perf_counter()

    # return time in milliseconds
    return 1000 * (end_time - start_time)

t = time_selection_sort(100)
print('Time:', t, 'ms')
