匹配日志文件中的两个模式并以表格形式输出

import re
from prettytable import PrettyTable

def match_and_output(log_file, pattern1, pattern2):
    # 读取日志文件
    with open(log_file, 'r') as file:
        log_content = file.read()

    # 匹配模式
    matches1 = re.findall(pattern1, log_content)
    matches2 = re.findall(pattern2, log_content)

    # 输出表格形式
    table = PrettyTable()
    table.field_names = ['Pattern 1', 'Pattern 2']

    # 确保两个模式匹配到的数量相等
    min_matches = min(len(matches1), len(matches2))
    for i in range(min_matches):
        table.add_row([matches1[i], matches2[i]])

    print(table)

# 示例调用
log_file = 'example.log'
pattern1 = r'pattern1'
pattern2 = r'pattern2'
match_and_output(log_file, pattern1, pattern2)
