使用DictReader时，如何跳过CSV中的一行记录？

码：

import csv
reader = csv.DictReader(open('test2.csv'))
# Skip first line
reader.next()
for row in reader:
    print(row)

错误：

Traceback (most recent call last):
  File "learn.py", line 3, in <module>
    reader.next()
AttributeError: 'DictReader' object has no attribute 'next'
