UnicodeDecodeError由python正則表達式

Question

我想用空格替換所有的標籤，所以我可以把我的昏迷分離文本放在另一個文件中的一行。現在，我的代碼如下所示：

from __future__ import print_function 
import re 
import ast 

f = open('sample_test.txt', 'r') 
g = open('sample_test1.txt', 'w') 

for line in f: 
     c = re.sub(r'\R', r' ', line.rstrip()) 
     print (c, file = g) 
f.close() 

現在的問題是，我得到這個錯誤：

UnicodeDecodeError: 'charmap' codec can't decode byte 0x98 in position 1944: character maps to <undefined>

打開文件作爲UTF-8，你也不需要一個正則表達式，如果你只想替換標籤：

import io 

with io.open('sample_test.txt', encoding="utf-8") as f, io.open('sample_test1.txt', 'w', encoding="utf-8") as g: 
    for line in f: 
     g.write(line.replace("\t"," "))
