在Python 2.7.4的包中,当您转到Lib -> email -> errors.py
时,模块中有一些有趣的东西。Python模块中的奇怪字符

"""email package exception classes."""
class MessageError(Exception):
"""Base class for errors in the email package."""
class MessageParseError(MessageError):
"""Base class for message parsing errors."""
class HeaderParseError(MessageParseError):
"""Error while parsing headers."""
class BoundaryError(MessageParseError):
"""Couldn't find terminating boundary."""
class MultipartConversionError(MessageError, TypeError):
"""Conversion to a multipart is prohibited."""
class CharsetError(MessageError):
"""An illegal charset was given."""
# These are parsing defects which the parser was able to work around.
class MessageDefect:
"""Base class for a message defect."""
def __init__(self, line=None):
self.line = line
class NoBoundaryInMultipartDefect(MessageDefect):
"""A message claimed to be a multipart but had no boundary parameter."""
class StartBoundaryNotFoundDefect(MessageDefect):
"""The claimed start boundary was never found."""
class FirstHeaderLineIsContinuationDefect(MessageDefect):
"""A message had a continuation line as its first header line."""
class MisplacedEnvelopeHeaderDefect(MessageDefect):
"""A 'Unix-from' header was found in the middle of a header block."""
class MalformedHeaderDefect(MessageDefect):
"""Found a header that was missing a colon, or was otherwise malformed."""
class MultipartInvariantViolationDefect(MessageDefect):
"""A message claimed to be a multipart but no subparts were found."""
这是模块的全部内容。除此之外,还有两个非常奇怪的字符,它们不会在预览中显示,并且不能被复制粘贴。 他们看起来像人类的棍子字符(记事本),我觉得它很有趣。
其中之一是前行
class MessageError(Exception):
"""Base class for errors in the email package."""
另一种是后
class CharsetError(MessageError):
"""An illegal charset was given."""
有没有人有一个想法,以什么这些字符在那里做什么?还是只是我的包?
你是什么意思的“不能复制粘贴”?你不能选择它们吗?粘贴他们产生一个空的盒子?一个空的空间?也许截图也是有帮助的。 – ASGM 2013-04-29 13:30:53
@ASGM,我可以选择,但是当我粘贴时,什么也没有显示出来。 – xylon97 2013-04-29 13:32:40
