python读取log文件

要Python中读取log文件，可以使用Python的内置库来实现。以下是一个示例代码，演示了如何读取log文件：

import logging

# 创建日志记录器
logger = logging.getLogger()
logger.setLevel(logging.DEBUG)

# 设置日志输出格式
format = logging.Formatter('%(asctime)s %(filename)s[line:%(lineno)d %(levelname)s %(message)s')

# 创建一个Handler用于将日志写入文件
logFile = './log.txt'
fh = logging.FileHandler(logFile, mode='a', encoding='utf-8')
fh.setLevel(logging.INFO)
fh.setFormatter(format)
logger.addHandler(fh)

# 读取log文件
with open(logFile, 'r', encoding='utf-8') as file:
    log_data = file.readlines()

# 打印log内容
for line in log_data:
    print(line.strip())

请注意，需要将上述代码中的`./log.txt`替换为实际的log文件路径。此代码将读取log文件的内容，并逐行打印出来。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
