import json

读取json文件

with open('investment.json', 'r', encoding='utf-8') as f: data = json.load(f)

统计每个轮次的投资事件次数

round_count = {} for item in data: round = item['融资轮次'] if round in round_count: round_count[round] += 1 else: round_count[round] = 1

按照投资事件次数降序排序，次数相同按照轮次升序排序

sorted_round_count = sorted(round_count.items(), key=lambda x: (-x[1], x[0]))

将结果写入result.txt文件中

with open('result.txt', 'w', encoding='utf-8') as f: f.write('投资轮次 投资事件次数\n') for round, count in sorted_round_count: f.write(f'{round} {count}\n')
