问题 I am running VS Code (Version 1.52) with extensions Jupyter Notebook (2020.12) and Python (2020.12) on MacOS Catalina. Context: I have problems getting Intellisense to work properly in my Jupyter Notebooks in VS Code. Some have had some success with adding these config parameters to the global settings of VS Code: "python.dataScience.runStartupCommands": [ "%config IPCompleter.greedy=True", "%config IPCompleter.use_jedi = False" ] I went ahead and added those as well but then had to realize

问题 Hello I am creating a Swing application to create a word document. I have made use of the Apache POI Java API for this purpose. But the problem is --> How do I set the word document to be read only after creation? I have heard of java.io.File.setReadOnly() method, but I don't know how to use it in this context. Here is the code: private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { try{ FileOutputStream outStream=new FileOutputStream("New.docx"); XWPFDocument doc =new

问题 Hi I'm having one Django web app where My model A contains 1000 records and I want to set a daily update limit for example if users are updating that data by uploading a .xls file then it should count how many records updated and once it is more than 500 then the user should get an Error message(Is there Any easy way to implement this at file processing level). Can Anyone help me how to implement this (Is there an SQLite parameter that I can mention in settings.py) below is my upload code.

问题 I just started using Jackson JSON parser, and I love it, but I've run into a problem with a JSON object I'm trying to parse. here's my current java code: public class resetPassword { private String id; private String key1; private String key2; public String getId() { return id; } public void setId(String id) { this.id= id; } public String getKey1() { return key1; } public void setKey1(String key1) { this.key1= key1; } public String getKey2() { return key2; } public void setKey2(String key2) {

问题 So I have the following qi skipper: template<typename Iterator> struct verilog_skipper : public qi::grammar<Iterator> { verilog_skipper() : verilog_skipper::base_type(skip) { namespace phx = boost::phoenix; skip = qi::ascii::space | qi::eol | line_comment; line_comment = (qi::lit("//") >> *(qi::char_ - qi::eol) >> *(qi::eol)); } qi::rule<Iterator> skip; qi::rule<Iterator> line_comment; }; and the following qi grammar: template <typename Iterator, typename Skipper = verilog_skipper<Iterator>

问题 I am trying to find the maximum sum of two elements in an array minus the distance between them. Specifically I am trying to calculate max{ a[i]+a[j]-|i-j| } I am currently stuck. I have obviously considered the naive approach (O(n^2)). However ,I am pretty sure there is a better ,more efficient approach (O(nlogn)) or even O(n). Can someone please help me on how to approach the problem. I would be grateful if anyone threw some hints or a simple idea to have something to start from. Sorting

问题 Please close if this is a duplicate, but this answer does not answer my question as I would like to print a list, not elements from a list. For example, the below does not work: mylist = [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15] print(%3s % mylist) Desired output: [ 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15] Basically, if all items in the list are n digits or less, equal spacing would give each item n+1 spots in the printout. Like setw in c++. Assume n is known. If I have missed a similar SO
