统计多个日志文件中的行数，按日期过滤，按文件名输出

import os
import re

log_folder = "/path/to/log/folder"
date_filter = "2022-01"  # 日期过滤条件，示例为筛选2022年1月的日志文件

log_files = []
log_counts = {}

# 遍历日志文件夹，获取符合条件的日志文件路径
for root, dirs, files in os.walk(log_folder):
    for file in files:
        if file.endswith(".log"):
            log_files.append(os.path.join(root, file))

# 按日期过滤日志文件
filtered_files = [file for file in log_files if re.search(date_filter, file)]

# 统计每个日志文件的行数
for file in filtered_files:
    with open(file, "r") as f:
        line_count = sum(1 for line in f)
        log_counts[file] = line_count

# 按文件名输出统计结果
for file, count in log_counts.items():
    print(f"文件名：{file}，行数：{count}")
