How to log python program activity in Mac OS X
提问by Oscar Carballal
I'm pretty new to Python programming so I have this question:
我对 Python 编程很陌生，所以我有这个问题：
How can I log a Python application activity into /var/log with Mac OS X?
如何使用 Mac OS X 将 Python 应用程序活动记录到 /var/log 中？
I tried using syslog module, but it does not seem to write anything. I tried also with the logging module, but I always run into a permission error.
我尝试使用 syslog 模块，但它似乎没有写任何东西。我也尝试过使用日志记录模块，但我总是遇到权限错误。
How can I do it?
我该怎么做？
Update:
更新：
import logging
import time
LOG_FILENAME = "/var/log/writeup.log" + time.strftime("%Y-%m-%d")
LOG_FORMAT = "%(asctime)s - %(filename)s - %(levelname)s - %(message)s"
log = logging.getLogger("main.py")
log.setLevel(logging.DEBUG)
ch = logging.FileHandler(LOG_FILENAME)
ch.setLevel(logging.DEBUG)
format = logging.Formatter(LOG_FORMAT)
ch.setFormatter(format)
log.addHandler(ch)

I found the solution. It seems that Mac OS X does not record any log activity lower than LOG_ALERT, so this does the trick
我找到了解决方案。似乎 Mac OS X 没有记录任何低于 LOG_ALERT 的日志活动，所以这就是诀窍
import syslog
# Define identifier
syslog.openlog("Python")
# Record a message
syslog.syslog(syslog.LOG_ALERT, "Example message")
This message is recorded on /var/log/system.log
此消息记录在 /var/log/system.log

You can use the command line tool "syslog" on os x, to get all syslog events.
您可以在 os x 上使用命令行工具“syslog”来获取所有 syslog 事件。

Here's a guide with about 5 steps you need to complete - they're straightforward, and it worked for me:
这是您需要完成的大约 5 个步骤的指南 - 它们很简单，对我有用：

Pay close attention to this step, as you have to make a few command calls there:
请密切注意这一步，因为您必须在那里进行一些命令调用：
sudo /usr/libexec/PlistBuddy /System/Library/LaunchDaemons/com.apple.syslogd.plist
...
Command: Add :Sockets:NetworkListener dict
Command: Add :Sockets:NetworkListener:SockServiceName string "syslog"
Command: Add :Sockets:NetworkListener:SockType string "dgram"

the problem is that the account you are running the script as does not have write permission to /var/log
问题是您运行脚本的帐户没有写入权限 /var/log
I do not know about OS X specifics, but I guess that syslog.syslog("message")should print something like (if it acts the way it does in Linux)
Feb 11 14:27:47 hostname python: messageto /var/log/messages
我不知道 OS X 的具体细节，但我想syslog.syslog("message")应该打印一些类似的东西（如果它像在 Linux 中一样）
Feb 11 14:27:47 hostname python: message来/var/log/messages
