Let's make an intentional syntax error... >>> print "Testing\" SyntaxError: EOL while scanning single-quoted string Please focus on the part of the error message that states "while scanning single-quoted string". How can Python claim it scanned a single-quoted string when I fed it with a double-quoted string? That is a quote type recognition bug in Python which should be fixed. The error message in this case should, however, be: SyntaxError: EOL while scanning double-quoted string |

It seems "single-quoted" doesn't mean the actual quotation sign used but rather how many you used. Compare the multiline triple quote syntax: $ cat foo.py """bar $ python foo.py File "foo.py", line 3 ^ SyntaxError: EOF while scanning triple-quoted string This shouldn't read sextuple-quoted string, should it? |

I have e-mailed Guido van Rossum about this. He replied: "Good find. Please file a bug on bugs.python.org." If that wasn't a bug, he wouldn't have said that, would he? |

This is not a bug in my opinion -- Robert has stated why. However, since you contacted Guido, let him decide. :) |

As the term "single-quoted string" is clearly ambiguous, I propose to change the error message to just "string" (or perhaps "string literal", but then you'd have to change the triple-quoted message to "triple-quoted string literal" too for consistency). |

OK, done so in r63068. |

It would be better to say "End of line while scanning string (<string>, line 1)" and "End of f... while scanning multi-line string (<string>, line 1)" These messages really need to be clear, so putting EOF for example (which I really don't know what it stands for) is really mind-bending. |
