为啥我的输出结果就是不对，求教

import sys

    # input_list = [2,3,2,3,2]
    # print(inputs_list)
    set_list = set(inputs_list)

    need_list = {}

    for i in set_list:
        need_list[i] = []

    for idx, num_ in enumerate(inputs_list):
        need_list[num_].append(idx)

    copy_inputs = [-1 for i in range(len(inputs_list))]
    for k, v in need_list.items():

            copy_inputs[v[0]] = v[1] + 1
            copy_inputs[v[1]] = v[0] + 1

        else:
            pass
    return copy_inputs

copy_inputs = process()
print('[', end='')
print(*copy_inputs, sep=',', end='')
print(']', end='')
