忽略/跳过带有筛选器[重复]的csv的第一行

Question

是否可以忽略或跳过CSV文件中带有filter的第一行？

filtered = filter(lambda p: celery == p[7],reader)
csv.writer(open(filename, 'w',newline=''), delimiter=',').writerows(filtered)

我试图读取和过滤只包含单词芹菜的第7行，但是因为过滤器一直在读取标题东西，它会弄乱下面的行。

                                                          Stuff

我想因为它找不到芹菜，所以它就切断了下面的线？

在构造过滤的代码之前，只需添加下一个代码：

通过调用迭代器的Next（）方法从迭代器中检索下一个项。如果给出默认值，则在迭代器用尽时返回默认值，否则引发StopIteration。

例子：

next(reader, None) # skips a line - default set to None
filtered = filter(lambda p: celery == p[7],reader)
