问题 Does the YYYY-MM-DD HH:MM:SS datetime format have a special name? I am writing a function that returns a date in this format and I'm trying to figure out what to call the function. 回答1: I can't find a source, but in my experience (25 years working as a systems programmer in UNIX environments) this format is referred to colloquially among engineers as Yoda Time. It's not valid ISO 8601 because it uses a space instead of a T to separate the date and time parts. 回答2: It looks a lot like ISO 8601

问题 I am having trouble calling a program with the Process class to start a program. The hierarchy to the executable is in under the bin directory while the current working directory needs to be under the lib directory. /project /bin a.out (this is what I need to call) /lib (this is where I need to be in order for a.out to work) I have set the WorkingDirectory = "path/lib" and the "FileName = "../bin/a.out" . However I am getting an error of: Unhandled Exception: System.ComponentModel

问题 I was hoping to trigger a Pub/Sub function (using functions.pubsub / onPublish) whenever a new Pub/Sub message is sent to a topic/subscription in a third-party project i.e. cross projects. After some research and experimentation I found that TopicBuilder throws an error if the topic name contains a / and it defaults to "projects/" + process.env.GCLOUD_PROJECT + "/topics/" + topic (https://github.com/firebase/firebase-functions/blob/master/src/providers/pubsub.ts). I also found a post in Stack

问题 I have a XML Schema that contains multiple imports which in turn contain imports. I need to generate semantically equal schema where all imports are inlined. I want to replace these: <xs:import namespace="http://some.name/" schemaLocation="./path/to/it.xsd"/> with the contents of referenced schemata. And I need to get output as a string, not as some internal representation. I tried Apache Xerces but did not find a way to write XSModel to a string. Is there? I tried Apache XmlSchema 2 but when

问题 How exactly is string[] args populated in a C# Main method? For instance, is white space stripped? Are any of the elements ever empty string or null? How are single and double quotes handled? MSDN doesn't explain how and merely says The parameter of the Main method is a String array that represents the command-line arguments 回答1: When you start a process, you can pass a string as your argument. How those are arranged and split up is entirely up to you. So if using the Windows command line,

问题 I am working on a program to migrate files from potentially big directory structures and many of them (approx. 1 million). My migration code already works quite well, and I am using a class to iterate to the directory structure, identify the files to migrate them sequentially one after another. Now I want to make better use of the available CPU resources of the targeted machine, and do those migrations asynchronously grabbing threads from a System.Threading.TThreadPool to execute these. I

问题 I have .zip archive with filename.xlsx inside it and I want to parse Excel sheet line by line. How to proper pass filename into pandas.read_excel in this case? I tried: import zipfile import pandas myzip=zipfile.ZipFile(filename.zip) for fname in myzip.namelist(): with myzip.open(fname) as from_archive: with pandas.read_excel(from_archive) as fin: for line in fin: .... but it doesn't seem to work, and the result was: AttributeError: __exit__ 回答1: You can extract your zip-file into a variable
