问题
I cannot see a significant difference between the two following lines.
Yet the first parses, and the latter, does not.
In [5]: n=""" \\"Axis of Awesome\\" """
In [6]: n="""\\"Axis of Awesome\\""""
File "<ipython-input-6-d691e511a27b>", line 1
n="""\\"Axis of Awesome\\""""
^
SyntaxError: EOL while scanning string literal
Is this a Python bug/feature/oddity, or have I missing something fundamental?
回答1:
The last four quote marks in
"""\\"Axis of Awesome\\""""
are parsed as """, i.e. end of string, followed by ", i.e. start of a new string literal. This new literal is never completed, though. Simple example:
>>> """foo""""bar"
'foobar'
>>> """foo""" "bar"
'foobar'
If you want to avoid this problem, then replace """ with r' or escape the ":
>>> """\\"Axis of Awesome\\\""""
'\\"Axis of Awesome\\"'
>>> r'\"Axis of Awesome\"'
'\\"Axis of Awesome\\"'
回答2:
Your last 4 quotation marks are being evaluated as "" & "" instead of what you're expecting it to be evaluated as " & """.
