python - 如何使用 Python 读取 utf-8 编码的文本文件

Question

我需要分析泰米尔语(utf-8 编码)的文本文件。我在 IDLE 接口(interface)上使用 Python 的 nltk 包。当我尝试读取界面上的文本文件时，这是我得到的错误。我该如何避免这种情况？

corpus = open('C:\\Users\\Customer\\Desktop\\DISSERTATION\\ettuthokai.txt').read()

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    corpus = open('C:\\Users\\Customer\\Desktop\\DISSERTATION\\ettuthokai.txt').read()
  File "C:\Users\Customer\AppData\Local\Programs\Python\Python35-32\lib\encodings\cp1252.py", line 23, in decode
    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x8d in position 33: character maps to <undefined>

Answer 1

由于您使用的是 Python 3，只需将 encoding 参数添加到 open() 即可:

corpus = open(
    r"C:\Users\Customer\Desktop\DISSERTATION\ettuthokai.txt", encoding="utf-8"
).read()
