问题 I am using the API for challonge and their url format is https://username:password@challonge.com/api/ However, when the use urllib2 in python to get this url, response = urllib2.urlopen('https://username:password@challonge.com/api/'), I get an error about a non-numerical port number.

问题 When teaching people about Matlab, it would be very nice if I could refer to Matlab's colon operator as something other than just "the colon operator". As you can read on this Mathworks blog, the operator has a number of different contexts. I'm referring specifically to the first use on that list, creating a list of numbers. Does anyone have a clever phrase they use to refer to this operation? 回答1: I would call it the "range operator". 回答2: Linear Space Vector Generator would also do I think

问题 I apologize for posting a duplicate-looking question, (I know, that there is a bunch of similar titled questions here), but none of the questions already present seems to suit my case. In short, what does the colon do here: <script> 'use strict'; foo: 1; //whatever else </script> I supposed this to be a syntax error, but it's not. And it's not a label, I think, since adding a line break foo; throws Uncaught SyntaxError: Undefined label 'foo' (though a doc page suggests exactly this, that it's

问题 I am learning javascript myself. There is a confusion with some javascript, price = 14; name = "Mary"; apples:5; //This line executing without error "orranges":6; //This line getting error alert(name); Those both lines can be used into a json object without any error. But when I am using those lines outside of json object, 2nd line ( "orranges":6; ) is getting error. Why is that ? And why is not giving error for the first line ( apples:5; ), is there any way that I can use it outside of json

问题 I am using a properties file to store my application's configuration values. In one of the instances, I have to store a value as xxx:yyy:zzz . When I do that, the colon is escaped with a back slash \ resulting in the value showing as xxx\:yyy\:zzz in the properties file. I am aware that the colon : is a standard delimiter of the Properties Java class. However I still need to save the value without the back slash \ . Any suggestions on how to handle this? 回答1: Put the properties into the

问题 I'm trying to read in a line from a file that contains a colon and exclamation point. When I echo that line, it only shows everything AFTER the colon. I need to keep the enabledelayedexpansion for more advanced code I will be doing in the do loop. But right now I just want to echo properly. Any help would be appreciated! File would say something like: ! 12345 APX: 6.32 Code I tried was: setlocal EnableDelayedExpansion cd C:\Users\jwagh\Desktop\ for /f "usebackq delims=" %%a in (test.txt) DO (

问题 I have condition part of my query as follows: ... where foo.bar like '%:%' the query would execute but with no result. I think it's because of the colon since it is a reserved char in HQL. So how can I escape it without sending the : as a parameter to my query. I have already used '%\:%' and '%\\:%' with no success. 回答1: I found a solution: q=q.replaceAll(":","'||unistr('\\003A')||'"); 来源： https://stackoverflow.com/questions/18614960/how-to-escape-colon-in-hql
