您可以一次从两个文件中消耗一行，将它们连接在一起并写入外文件。该
csv模块使事情变得更清洁。
import csvwith open('A','rb') as f1, open('B','rb') as f2, open('out.csv','wb') as w: writer = csv.writer(w) r1,r2 = csv.reader(f1),csv.reader(f2) while True: try: writer.writerow(next(r1)+next(r2)) except StopIteration: break正如@RogerPate指出的那样，您可以使用
itertools.izip（就像
zip您在python3中一样）进行此处理
from itertools import izipimport csvwith open('A','rb') as f1, open('B','rb') as f2, open('out.csv','wb') as w: writer = csv.writer(w) for r1,r2 in izip(csv.reader(f1),csv.reader(f2)): writer.writerow(r1+r2)
