Question

我是Python的新手，正在从工作中查看一些代码。

我注意到有很多行包含row[0].encode('ascii', 'ignore')。

我做了一些阅读，看起来它正在从unicode转换为字节。

它只是一种将字符串从u'string'转换为字符串的方法吗？

    encode(...)
        S.encode([encoding[,errors]]) -> object

        Encodes S using the codec registered for encoding. encoding defaults
        to the default encoding. errors may be given to set a different error
        handling scheme. Default is 'strict' meaning that encoding errors raise
        a UnicodeEncodeError. Other possible values are 'ignore', 'replace' and
        'xmlcharrefreplace' as well as any other name registered with
        codecs.register_error that is able to handle UnicodeEncodeErrors.

因此它将asicode字符串编码为ascii并忽略错误

>>> "hello\xffworld".encode("ascii")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character '\xff' in position 5: ordinal not in range(128)

VS

>>> "hello\xffworld".encode("ascii", "ignore")
b'helloworld'

Python：.encode（＆＃39; ascii＆＃39;，＆＃39;忽略＆＃39;）做什么？
