问题 This question already has answers here : What does a colon in a struct declaration mean, such as :1, :7, :16, or :32? (3 answers) Closed 4 years ago .

I've seen that IIS has a problem with letting colons into URLs. I also saw the suggestions others offered here . With the site I'm working on, I want to be able to pass titles of movies, books, etc., into my URL, colon included, like this: mysite.com/Movie/Bob:The Return This would be consumed by my MovieController , for example, as a string and used further down the line. I realize that a colon is not ideal. Does anyone have any other suggestions? As poor as it currently is, I'm doing a find-and-replace from all colons (:) to another character, then a backwards replace when I want to consume

I'm making a library, and I often inspect the result of Closure Compiler's output to see how it's doing things (I do have unit tests, but I still like to see the compiled code for hints of how it could compress better). So, I found this very weird piece of code, which I never seen before. variable : { some(); code() } Note: this is not an object literal! Also, there is no ? anywhere that would make it a ?: conditional . That code is in a regular function block (an IIFE ). variable , in this case, is an undefined variable. There's no code making it true, false, or whatever , and just to make

问题 I am trying to create an xml tree from a JSON object using lxml.etree. Some of the tagnames contin a colon in them something like :- 'settings:current' I tried using '{settings}current' as the tag name but I get this :- ns0:current xmlns:ns0="settings" 回答1: Yes, first read and understand XML namespaces. Then use that to generate XML-tree with namespaces:u >>> MY_NAMESPACES={'settings': 'http://example.com/url-for-settings-namespace'} >>> e=etree.Element('{%s}current' % MY_NAMESPACES['settings

问题 I want a user to input time, so like 12:00, but I need to figure out a few things and I am wicked lost. Can I limit the text to 5 characters and how? Can I have a colon embedded in the code so that it cant be deleted by the user? Finally, can I take that code and verify that it is only the digits (ignoring the colon of course) 回答1: The answer is to use a JFormattedTextField and a MaskFormatter. For example: String mask = "##:##"; MaskFormatter timeFormatter = new MaskFormatter(mask);

Opening filenames with colon (“:”) in Windows 7

我的梦境 提交于 2019-11-30 15:11:53
I am writing a Python app that should run in both Windows and Linux, but am having an issue with one of the filenaming conventions. I need to load a JSON file that has a colon in its name. However, with Windows 7 it doesn't seem to be possible, at least not directly. These files are stored on a NFS drive thus we are able to see it in Windows 7, but cannot open them. Does anyone have a workaround as to how it may be possible to read the JSON file containing a colon in Windows 7 using Python? One possible workaround we have (that we'd like to avoid) is to SSH into a Linux box, echo the contents

Python: single colon vs double colon

↘锁芯ラ 提交于 2019-11-30 12:59:53
What is the difference between single and double colon in this situation? data[0:,4] vs data[0::,4] women_only_stats = data[0::,4] == "female" men_only_stats = data[0::,4] != "female" I tried to replace data[0::,4] with data[0:,4] and I see no difference. Is there any difference in this or another case? data is 2-dimensional array with rows like ['1' '0' '3' 'Braund, Mr. Owen Harris' 'male' '22' '1' '0' 'A/5 21171' '7.25' '' 'S'] No , there is no difference. See the Python documentation for slice : From the docs: a[start:stop:step] The start and step arguments default to None. Slice objects

Bash colon operator in variable substitution? [duplicate]

This question already has an answer here: Usage of :- (colon dash) in bash 2 answers I inherited some bash code and these two lines are bewildering me: branch_name=`git describe --contains --all HEAD` branch_name=${branch_name:-HEAD} My understanding of the : colon operator is that is creates a substring based on an index so using a string, -HEAD in this case, does not make any sense. This takes the variable branch_name , if it is defined. If it is not defined, use HEAD instead.
