Python 3.2 skip a line in csv.DictReader

Question

How do I skip a line of records in a CSV when using a DictReader?

Code:

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

Error:

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

Answer 1

You use next(reader) instead.

Answer 2

从Python 2.6开始，你应该使用next（foo）而不是foo.next（）。

Answer 3

It was considered a mistake in python2 to have the method called next() instead of __next__()

next(obj) now calls obj.__next__() just like str , len etc. as it should.

You usually wouldn't call obj.__next__() directly just as you wouldn't call obj.__str__() directly if you wanted the string representation of an object.

Handy to know if you find yourself writing unusual iterators
