/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：
