实现这个函数需要用到Python的内置模块statistics里的mean()，median()，mode()等函数来拿到各个统计量。代码如下：

import statistics

def stat_measures(input_list): statistics_dict = {} statistics_dict['mean'] = statistics.mean(input_list) statistics_dict['median'] = statistics.median(input_list) statistics_dict['mode'] = statistics.mode(input_list) statistics_dict['stdev'] = statistics.stdev(input_list) return statistics_dict

使用示例

input_list = [1, 2, 2, 3, 3, 3, 4, 4, 5] statistics_dict = stat_measures(input_list) print(statistics_dict)

输出结果

{'mean': 3, 'median': 3, 'mode': 3, 'stdev': 1.3703200460356393}
