使用UTF-8打開文件進行讀取

Question

我正在使用下面的代碼，但需要打開它才能使用指定的utf-8進行讀取。我該怎麼做？

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

Answer 1

使用open功能codecs模塊：

import codecs 

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

默認情況下，codecs.open功能，rb打開文件（閱讀二進制）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.
