创建日志txt文件

Question

我正在尝试用 python 创建一个 log_file.txt 。 所以，每当我每次运行脚本时，它都应该生成新的日志文件。

例如：

日志文件 日志文件1 日志文件2 。 。 。 .

def log(message):
    try:
        counter = 1
        # Format the log message with current date and time
        log_message = f"[{datetime.now().strftime('%Y-%m-%d %H:%M:%S')}] {message}\n"
        # Write the message to the log file
        with open("log_file.txt", "a") as log_file:
            log_file.write(log_message)
    except Exception as e:
        print(f"Error occurred while logging: {e}")

这是我尝试过的。

Answer 1

import os
from datetime import datetime

def log(message):
    try:
        counter = 1
        while os.path.exists(f"log_file{counter}.txt"):
            counter += 1
        log_message = f"[{datetime.now().strftime('%Y-%m-%d %H:%M:%S')}] {message}\n"
        with open(f"log_file{counter}.txt", "a") as log_file:
            log_file.write(log_message)
    except Exception as e:
        print(f"Error occurred while logging: {e}")

log("This is a log message.")

请尝试这个
