有個table文件， 有時候需要處理header ， 可以用linecache 模塊
#!/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("NameProbe\tdata")
for p in d:
for x in d[p]:
#print(x, d[p])
print("{0}\t{1}".format(p, x))當然也可以用 fileinput 模塊
