读文件字符串分割最后一个带了\n，怎么处理？

[wklken]

文件为多行
A B C
D E F
1 2 3
字符之间用\t分割

用file.readlines读入
遍历每一样，用split("\t")切

然后得到：
['A', 'B', 'C\n']

囧，因为我要拼东西的，结果最后一个带了\n，换行了

怎么处理呢？？？？

我本意想写一个数据格式转换的模块，刚学没几天，哎,求教，谢谢

#!/usr/bin/python
def read_file(path):
f = open(path,"r")
lines = f.readlines()
f.close()
return lines


def one_line_proc(instr,insp,total,to,outsp):
parts=instr.split(insp)
print(parts)
if len(parts) != len(to):
print("Error!%s be seplited by %s into %d,not equals to the tuple length")

toindex = 0
outline=""
for i in range(1,total+1):
if toindex!=len(to) and i==to[toindex]:
outline+=parts[toindex]
toindex+=1
else:
outline+="0"
if i!=total:
outline+=outsp
#print(" "+outline)
return outline

def process(inpath,insp,total,to,outpath,outsp):
lines = read_file(inpath)
f = open(outpath,"w")
result=[]
for line in lines:
print(line),
outline = one_line_proc(line,insp,total,to,outsp)
print(outline)
print("-------")
result.append(outline)
f.writelines(result)
f.close()

inpath="source"
insp="\t"
total=10
to=(1,3,5)

outpath="result"
outsp="-"

process(inpath,insp,total,to,outpath,outsp)

line.strip('\n').split('\t')
