Python等同于PHP的memory_get_usage（）？

Python等同于PHP的memory_get_usage（）？

/proc/self/status

以下代码为Linux和其他系统提供了一个简单的解决方案，我在我的项目中使用了以下代码：

def memory_usage():    """Memory usage of the current process in kilobytes."""    status = None    result = {'peak': 0, 'rss': 0}    try:        # This will only work on systems with a /proc file system        # (like Linux).        status = open('/proc/self/status')        for line in status: parts = line.split() key = parts[0][2:-1].lower() if key in result:     result[key] = int(parts[1])    finally:        if status is not None: status.close()    return result

它返回当前和峰值驻留内存大小（这可能是人们在谈论应用程序使用多少RAM时的意思）。很容易扩展它以从

/proc/self/status

文件中获取其他信息。

出于好奇：的完整输出

cat /proc/self/status

如下所示：
