python csv阅读器，从第二行开始循环

Question

在 python 2.7.3 中，如何从第二行开始循环？例如

first_row = cvsreader.next();
for row in ???: #expect to begin the loop from second row
    blah...blah...

Answer 1

first_row = next(csvreader)  # Compatible with Python 3.x (also 2.7)
for row in csvreader:  # begins with second row
    # ...

测试它是否真的有效:

>>> import csv
>>> csvreader = csv.reader(['first,second', '2,a', '3,b'])
>>> header = next(csvreader)
>>> for line in csvreader:
    print line
['2', 'a']
['3', 'b']
