使用UTF-8打开文件进行读取

Question

我正在使用下面的代码，但需要打开它才能使用指定的utf-8进行读取。我该怎么做？

infile = file(logPath) 
lines = infile.readlines() 

Answer 1

使用open功能codecs模块：

import codecs 

with codecs.open(logPath, encoding='utf8') as infile: 
    lines = infile.readlines() 

默认情况下，codecs.open功能，rb打开文件（阅读二进制）模式：

def open(filename, mode='rb', encoding=None, errors='strict', buffering=1):

... 
    Files are always opened in binary mode, even if no binary mode 
    was specified. This is done to avoid data loss due to encodings 
    using 8-bit values. The default file mode is 'rb' meaning to 
    open the file in binary read mode.
