#!/usr/bin/env python
# -*- coding: ascii -*-
import linecache
import fileinput
import sys
from collections import defaultdict
inputFile = sys.argv
headerLine = linecache.getline(inputFile, 1).strip()
#print(headerLine)
Probenames = headerLine.split("\t")
inputH = open(inputFile, "r")
d = defaultdict(list)
for line in inputH:
if "Sample" not in line:
z = line.rstrip().split("\t")
for num, p_data in enumerate(z):
if p_data != "":
d].append(p_data)
inputH.close()
print("NameProbe\tdata")
for p in d:
for x in d:
#print(x, d)
print("{0}\t{1}".format(p, x))
当然也可以用 fileinput 模块
