问题 I just left the PC at work (using Python 2.7) and had a script that I was just finishing up (reproduced below). It ran fine at work, I just wanted to add one or two things. But I came home and am using my Mac's version of Python (3.2.2) and I get the following error: Traceback (most recent call last): File "/Users/Downloads/sda/alias.py", line 25, in <module> for row_2 in in_csv: File "/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/encodings/ascii.py", line 26, in decode

问题 I am getting the abovementioned error message when trying to validate my 55 mb XML file in Notepad++. The first enocountered error is here (line 1441520 out of 22258651): Screenshot from Notepad++ I have turned on Show all characters. Nothing suggests that there should be any illegal characters at the end of the line. As you can see on the screenshot there are no other hidden characters than CR+LF.

问题 In my unit test I have the following code that checks whether thrown error is of expected type. It is done with two identical statements one of which doesn't compile: enum Error: ErrorType { case SomeExpectedError case SomeUnexpectedError } func functionThatThrows() throws { throw Error.SomeExpectedError } // 1) this compiles fine XCTAssertThrowsError(try functionThatThrows()) { (error) in switch error { case Error.SomeExpectedError: break //everything is fine case Error.SomeUnexpectedError:

问题 here is the relevent code snippet: public static Rand searchCount (int[] x) { int a ; int b ; int c ; int d ; int f ; int g ; int h ; int i ; int j ; Rand countA = new Rand () ; for (int l= 0; l<x.length; l++) { if (x[l] = 0) a++ ; else if (x[l] = 1) b++ ; } } return countA ; } (Rand is the name of the class that this method is in) when compiling it get this error message: Rand.java:77: illegal start of type return countA ; ^ what's going wrong here? what does this error message mean? 回答1:

问题 This question already has answers here : Why {} != ( {} ) in JavaScript? (2 answers) Closed 5 years ago . Why is it that when i type {} === null into the console it throws SyntaxError: Unexpected token === null === {} gives me false as expected. 回答1: Because {} is treated as an empty block.

问题 UPDATE bestall SET view = t1.v, rawview = t1.rv FROM bestall INNER JOIN beststat as t1 ON bestall.bestid = t1.bestid this query gives syntax error near 'FROM bestall INNER JOIN beststat as t1 ON bestall.bestid = t1.bestid' at line 3 any reasons? 回答1: That isn't valid MySQL syntax. It is valid in MS SQL Server, however. For MySQL, use: UPDATE bestall JOIN beststat AS t1 ON bestall.bestid = t1.bestid SET view = t1.v, rawview = t1.rv MySQL requires the update tables to come before the SET clause

问题 I recently inherited some code that someone else had written. I discovered that everywhere in the code that a directory was opened for reading, it was never closed because the original developer had a syntax problem - he was using the close function to try to close a directory handle instead of the closedir function. The code was something like this: opendir( DIR, $dir ) or die "Cannot open $dir: $!\n"; @files = readdir( DIR ); close( DIR ); (Which is another good point that is made in Perl
