syntax-error

问题 I've checked and rechecked and looked over and over at it but can't understand what's wrong with it.

问题 I'm on Windows and I'm using PyScripter. For some reason everything results in a syntax error, even code that very obviously does not have a syntax error.

Did I download Python wrong, am I setting it up wrong, or what? 回答1: Are you using Python 3? The print function in Python three must use parentheses: a = 6 print(a) 回答2: I think

问题 This question already has answers here : I'm getting an IndentationError. How do I fix it? (4 answers) Closed last year . I'm absolutely pulling my hair out over this. The if/elif statement in this function throws a syntax error on the elif line. To me there are no obvious syntax problems.

I'm sure there's something I don't see. def higherhighlight

问题 The following hash is causing a syntax error. I assume it is because of the funky characters. Any way to fix this? I'm using macvim, in case that matters. { :en => ['English', 'en_US'], :es => ['español', 'es_MX'], :fr => ['français', 'fr_FR'], :de => ['Deutsch', 'de_DE'], :ru => ['русский', 'ru_RU'], :zh => ['中国的', 'zh_CN'], :ar => ['العربية', 'ar_AR'], } 回答1: If this is Ruby 1.9, then you can set the magic comment to tell Ruby this is a UTF8 file instead of ASCII: How does the magic comment

问题 In Objective-C, the compiler is complaining about the following line of code: if ([self getLength(self.identifier)] < givenWidth * kMarginAllowance) This is getting the error "Expected ']'", and the caret below the text is on the parenthesis exactly after "getLength". My suspicion is that my [self getLength(self.identifier)] is wrong in how it combines things. What I want to say is "Fetch this object's identifier, and call this object's getLength() method." I've tried a couple of permutations
