Question

我需要将连接错误记录到log.txt。 Windows是俄语。我的代码：

    # e is a name for "requests.ConnectionError" form Windows if server is not avilable
    # I take error and cut from it text I need and convert it to str
    e_warning = str(e.args[0].reason)
    # I search text I need in string with "re"
    e_lst = re.findall('>:\s(.+)', e_warning)
    # I create string again from list "re" gives me
    e_str = ''.join(e_lst)
    # I Convert string to bytes
    e_str_unicode = codecs.encode(e_str, 'utf-8')
    # It is a message to warning window
    e_str_utf = codecs.decode(e_str_unicode, encoding='utf-8')
    messagebox.showerror(title='Connection error', message=e_str)
        with codecs.open('log.txt', 'a', encoding='utf-8') as log:
        log.write(strftime(str("%H:%M:%S %Y-%m-%d") + str(e_str_unicode) + '\n'))

如果我使用＆＃34; e_str_utf＆＃34;在最后一行，它给了我：

UnicodeEncodeError: 'locale' codec can't encode character '\u041f' in position 72: Illegal byte sequence

有道理 - 72是俄罗斯的第一封信。如果我使用＆＃34; e_str_unicode＆＃34;在最后一行它没有错误，但在日志文件中我看到：

我可以理解 encoding =＆＃39; utf-8＆＃39;

with codecs.open('log.txt', 'a', encoding='utf-8') as log:

应该在我的文件中保存utf-8代码中的UNICODE字节，但由于某种原因它忽略了编码设置......为什么？

Answer 1

首先：什么是编解码器codecs.open('log.txt', 'a', encoding='utf-8')？

第二：这不对strftime(str("%H:%M:%S %Y-%m-%d") + str(e_str_unicode) + '\n')它应该是strftime("%H:%M:%S %Y-%m-%d") + e_str_unicode + '\n'

这是一个简单的例子：

from time import strftime
text = input()
print(text)

with open('log.text', 'a', encoding='utf-8') as log:
    message = strftime("%H:%M:%S %Y-%m-%d") + '=>' + text + '\n'
    log.write(message)

Python 3.6.1中输出文件中的Unicode符号
