从公认的答案来看。。。You can use triple-quoted strings. When they're not a docstring (first thing in a class/function/module), they are ignored.

这根本不是真的。与注释不同，三引号字符串仍然被解析，并且必须在语法上有效，而不管它们在源代码中出现在哪里。

如果你试图运行此代码。。。def parse_token(token):

"""

This function parses a token.

TODO: write a decent docstring :-)

"""

if token == '\\and':

do_something()

elif token == '\\or':

do_something_else()

elif token == '\\xor':

'''

Note that we still need to provide support for the deprecated

token \xor. Hopefully we can drop support in libfoo 2.0.

'''

do_a_different_thing()

else:

raise ValueError

你要么。。。ValueError: invalid \x escape

…在Python2.x或。。。SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 79-80: truncated \xXX escape

…在Python 3.x上

做被解析器忽略的多行注释的唯一方法是。。。elif token == '\\xor':

# Note that we still need to provide support for the deprecated

# token \xor. Hopefully we can drop support in libfoo 2.0.
