csv读取

# -*- coding: utf-8 -*-
import os

newline, s = ("", "")
try:
    f = open(u"简易记账.csv")
except IOError:
    print "文件不存在！".decode('utf8').encode('gbk')
    sys.exit()
f1 = open(u"结果.txt", 'w')
total, n = (0, 1)
for line in f:
    if n == 1:
        n += 1
        continue
    mylist = line.decode('utf8').encode('gbk').split(',')
    del mylist[0:4]
    del mylist[2]
    date = mylist[0][0:10]
    date = date.replace('-', '')
    money = float(mylist[1])
    total += money
    s = '{0} {1:>3.0f} {2}'.format(date, money, mylist[2])   
    newline += s
newline += '{0:>8s} {1:>3.0f}'.format("合计:".decode('utf8').encode('gbk'), total)
f1.write(newline)
f1.close()
f.close()

raw_input("请按任意键继续！".decode('utf8').encode('gbk'))
每次都要解码
