如何使用python删除ml.transcription文件中句子开头和结尾的标记并将其保存到newml.transcription文件中？

Question

当前格式:我有一个ml.transcription文件，它以以下方式由句子组成-(在句子的开头和结尾都有标签，后面跟一个序列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

#!/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()

我收到的错误：

Fo.write(行，"\n")

TypeError:函数只接受1个参数(给定2个)

虽然上述代码中的逻辑是正确的，并打印出所需的输出，但此错误会预先创建一个problem.Thanks。

这是一种粗糙的方式：

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]

上面打印到屏幕上，您可以通过管道将其输出到一个文件中。它假设在<r>之后以及在</r>之前和之后总是有一个空格。它还假定每行都以换行符结束。
