核心提示: 1. 写入并生成csv文件代码:# coding: utf-8import csvcsvfile = file('csv_test.csv', 'wb')writer = csv.writer(csvfile)writer.writerow(['姓名', '年龄

 1. 写入并生成csv文件
代码:
# coding: utf-8

import csv

csvfile = file('csv_test.csv', 'wb')
writer = csv.writer(csvfile)
writer.writerow(['姓名', '年龄', '电话'])

data = [
('小河', '25', '1234567'),
('小芳', '18', '789456')
]
writer.writerows(data)

csvfile.close()

wb中的w表示写入模式,b是文件模式
写入一行用writerow
多行用writerows

2. 读取csv文件
代码:
# coding: utf-8

import csv

csvfile = file('csv_test.csv', 'rb')
reader = csv.reader(csvfile)

for line in reader:
print line

csvfile.close()

运行结果:
[email protected]:~/python/example# python read_csv.py
['\xe5\xa7\x93\xe5\x90\x8d', '\xe5\xb9\xb4\xe9\xbe\x84', '\xe7\x94\xb5\xe8\xaf\x9d']
['\xe5\xb0\x8f\xe6\xb2\xb3', '25', '1234567']
['\xe5\xb0\x8f\xe8\x8a\xb3', '18', '789456']
