Python读写csv文件
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:
root@he-desktop:~/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']
