这是格式很漂亮的输入，您可以通过拆分每一行轻松地获取列和数据列表，然后为其创建字典。
这是一个没有正则表达式的简单脚本
lines = open("/proc/net/dev", "r").readlines()columnLine = lines[1]_, receiveCols , transmitCols = columnLine.split("|")receiveCols = map(lambda a:"recv_"+a, receiveCols.split())transmitCols = map(lambda a:"trans_"+a, transmitCols.split())cols = receiveCols+transmitColsfaces = {}for line in lines[2:]: if line.find(":") < 0: continue face, data = line.split(":") faceData = dict(zip(cols, data.split())) faces[face] = faceDataimport pprintpprint.pprint(faces)它输出
