python - 使用UTF-8打开文件进行读取

Question

我正在使用下面的代码，但需要打开它以指定 utf-8 进行阅读。请问我该怎么做？

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

使用codecs的open功能模块:

import codecs

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

默认情况下，codecs.open函数，以rb(读取二进制)模式打开文件:

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.
