syntax-error

问题 This code works when I try it from a .py file, but fails in the command line interpreter and Idle. >>> try: ... fsock = open("/bla") ... except IOError: ... print "Caught" ... print "continue" File "<stdin>", line 5 print "continue" ^ SyntaxError: invalid syntax I'm using python 2.6 回答1: With Python 3, print is a function and not a statement, so you would need parentheses around the arguments, as in print("continue") , if you were using Python 3. The caret, however, is pointing to an earlier

问题 SyntaxError: Non-UTF-8 code starting with '\x90' in file C:\Python36\python.exe on line 1, but no encoding declared I don't understand why it shows me that when I want to open the interpreter. Can someone help me please? 回答1: Ok, it's a wrong value for PYTHONSTARTUP which was asking me a problem. Thank you all ! 回答2: Python 3 assumes scripts are saved with UTF-8 encoding. The script being executed (from PYTHONSTARTUP?) is not UTF-8-encoded. If you know the encoding, you can add it to the top

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . My php script directs to a url depending on which submit button was pressed. However, when I run the test I'm getting an error saying line 4 contains an unexpected ":" but my line 4 is my header script with the url? I'm confused because I have other scripts similar to this and they don't give me that error. Can

问题 My Eclipse worked fine a couple of days ago before a Windows update. Now I get error messages whenever I'm trying to do anything in Eclipse. Just a simple program as this will display a bunch of error messages: package lab6; public class Hellomsg { System.out.println("Hello."); } These are the errors I receive on the same line as I have my "System.out.println": "Multiple markers at this line - Syntax error, insert ")" to complete MethodDeclaration - Syntax error on token ".", @ expected after

问题 I am working with an excel file and I am trying to "map" some values with the vLookUp function. The first parameter of the vLookUp function is giving me headaches: The function works with certains values (typed by hand in a text format)...but doesnt work with pre-generated values (the sames ones...but generated from an ERP system..). I checked to make sure that I was looking for "same nature" values ( text vs text ) ...but I can't find out why the first 3 values (typed by hand) are fine...

问题 Only at the checkout and on individual product pages I am getting the following error in the console log: VM35594:1 Uncaught SyntaxError: Unexpected token u in JSON at position 0 at JSON.parse (<anonymous>) at run (layout.min.js:9) at app.min.js:1 at main.min.js:2 at Object.execCb (require.min.js:112) at Module.check (require.min.js:56) at Module.<anonymous> (require.min.js:72) at require.min.js:11 at require.min.js:74 at each (require.min.js:3) I am using a one page checkout extension, but

问题 Also see the Why can't I end a raw string with a backslash? and Why can't Python's raw string literals end with a single backslash? questions and related answers. In my Python 2 program I use a lot of literal strings with embedded backslashes. I could use another backslash to escape each of these backslashes (eg: "red\\blue" ) or use Python raw strings (eg: r"red\blue" ). I have standardised on the raw string method which works well in all cases except one. If I want to represent a double

问题 Given a list of floats named 'x', I would like to create a dict mapping each x in x[1:-1] to it's neighbors using a dict comprehension. I have tried the following line : neighbours = {x1:(x0,x2) for (x0,x1,x2) in zip(x[:-2],x[1:-1],x[2:])} However, the syntax seems to be invalid. What am I doing wrong? 回答1: Dict comprehensions are only available in Python 2.7 upwards. For earlier versions, you need the dict() constructor with a generator: dict((x1, (x0,x2)) for (x0,x1,x2) in zip(x[:-2],x[1:-1

问题 Why is this function invalid? def request(method='get',resource, meta={}, strip=true) end unexcpected ')' expecting keyword_end Thank you! 回答1: In Ruby, you can't surround a required parameter with optional parameters. Using def request(resource, method='get', strip=true, meta={}) end will solve the issue. As a thought experiment, consider the original function def request(method='get',resource, meta={}, strip=true) end If I call that method as request(object) , the desired behavior is fairly

问题 I have a problem with Visual Studio on a C# solution. It displays totally random errors, but the projects build. Right now, I have 33 files with errors, and I can see red squiggly lines in all of them. I tried cleaning / rebuilding the solution, closing Visual Studio and even restarting my computer. I also made sure to do the steps described in Debugging runs even with compiler's errors in Visual Studio. I can modify .cs files and I see the changes in the solution. Does anyone have an idea
