读取 ` .csv ` 文件，获取Email地址，用逗号串联，存入文本文件。最后统计取得的Email个数：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import csv

output = open('out.txt', 'wb') <!--more-->    with open('contact.csv', 'rb') as csvfile:
    spamreader = csv.reader(csvfile, delimiter=' ', quotechar='|')
    for row in spamreader:
        for item in row:
            output.write(item + ',')
output.close()

result = open('out.txt', 'rb')
data = result.read()
print data.count('@')
out.close()
