python查找报告最多的月份

# 读取报告数据
with open('report_data.txt', 'r') as file:
    lines = file.readlines()

# 提取报告月份
months = []
for line in lines:
    report_date = line.split(',')[0]  # 假设报告数据格式为 "日期,其他内容"
    month = report_date.split('-')[1]  # 假设日期格式为 "年-月-日"
    months.append(month)

# 统计每个月份的报告数
month_count = {}
for month in months:
    if month in month_count:
        month_count[month] += 1
    else:
        month_count[month] = 1

# 找到报告数最多的月份
max_count = max(month_count.values())
most_common_months = [month for month, count in month_count.items() if count == max_count]

print("报告最多的月份是:")
for month in most_common_months:
    print(month)
