我在这里有包含同数据，但排序不一样的两个文件。我将第一个文件 “ref.de-en.test.txt” 按第二个文件 “test_2017.en” 来重新排序，最后重新排序的数据输入到 “sent.txt” 。它的实现代码如下：
def read_text_file(filename):
with open(filename, "r") as f:
output = [line.strip() for line in f]
return output
file1_path = 'ref.de-en.test.txt'
file2_path = 'tok/test_2017.en'
file1 = read_text_file(file1_path)
file2 = read_text_file(file2_path)
assert len(file1) == len(file2), '源句和目标句的长度必须相等.'
right_list = []
for i in range(len(file2)):
for j in range(len(file1)):
if file2[i] == file1[j]:
right_list.append(j)
right_sen_list = []
for i in right_list:
tgt = file1[i]
right_sen_list.append(tgt)
with open('sent.txt', 'w', encoding='utf-8') as f:
f.write('n'.join(right_sen_list) + 'n')
