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()
