如何删除ml.transcript文件中句子开头和结尾的标记，并使用python将其保存在newml.transcript文件中？

Question

当前格式：我有一个ml.transcription文件，它由以下方式的句子组成-（在句子的开头和结尾有标记，后面是序列id）

 1. <r>The quick brown fox jumps over a lazy dog </r> (umnle_001_001)
 2. <r> I think we should go get it now </r> (umnle_001_002)
 3. ......................................................
 4. <r> When I travel, I prefer to travel by air </r> (umnle_001_129)
 5. <r> The law was changed </r> (umtci_001_001)
 6. <r> This soup needs more salt </r> (umtci_001_002)
 7. .................................................
 8. .................................................
 9. <r> Tom sat two rows ahead of me </r> (umtci_001_197)

所需格式：我需要将所需结果保存在名为newml.transcription的新文件中，转换后所需格式如下-

 1. umnle_001_001 The quick brown fox jumps over a lazy dog
 2. umnle_001_002 I think we should go get it now
 3. ......................................................
 4. umnle_001_129 When I travel, I prefer to travel by air
 5. umtci_001_001 The law was changed
 6. umtci_001_002 This soup needs more salt
 7. ......................................................
 8. ......................................................
 9. umtci_001_197 Tom sat two rows ahead of me

---------------代码------------------------------------------

#!/usr/bin/env python

fo = open(" ml.transcription", "r")
y_list = []
for line in fo.readlines():
    a1 = line [-15:-2]
    a2 = line [4:]
    y = str(a1)+ " "+ str(a2)
    a3 = y[:-22]
    y_list.append(a3)
    print(a3)
fo.close()
fo = open("newml.transcription", "w")
for lines in y_list:
    fo.write(lines,"\n")
fo.close()

我得到的错误：

fo.write（行，“\n”）

TypeError:函数正好接受1个参数（给定2个）

虽然上述代码中的逻辑是正确的，并且打印出了所需的输出，但是这个错误产生了一个问题。提前谢谢

一种粗糙的方法：

import re
with open("input", "r") as input:
    for line in input:
        print line.split("</r> ")[1][2:-2] + " " + line.split("r>")[1][1:-3]

上面的打印到屏幕上，你可以通过管道把它传输到一个文件中。 它假定在<r>之后以及</r>之前和之后总是有一个空格。它还假定每行以换行符结束
