有个table文件， 有时候需要处理header ， 可以用linecache 模块
代码语言：javascript复制#!/usr/bin/env python
# -*- coding: ascii -*-
import linecache
import fileinput
import sys
from collections import defaultdict
inputFile = sys.argv[1]
headerLine = linecache.getline(inputFile, 1).strip()
#print(headerLine)
Probenames = headerLine.split("t")[1:]
inputH = open(inputFile, "r")
d = defaultdict(list)
for line in inputH:
if "Sample" not in line:
z = line.rstrip().split("t")[1:]
for num, p_data in enumerate(z):
if p_data != "":
d[Probenames[num]].append(p_data)
inputH.close()
print("NameProbetdata")
for p in d:
for x in d[p]:
#print(x, d[p])
print("{0}t{1}".format(p, x))当然也可以用 fileinput 模块
