问题 How do I able to replace: ((90+1)%(100-4)) + ((90+1)%(100-4/(6-4))) - (var1%(var2%var3(var4-var5))) with XYZ((90+1),(100-4)) + XYZ((90+1),100-4/(6-4)) - XYZ(var1,XYZ(var2,var3(var4-var5))) with regex? Thanks, J 回答1: this doesn't really look like a very good job for a regex. It looks like you might want to write a quick recursive descent parser instead. If I understand you correctly, you want to replace the infix operator % with a function name XYZ? So (expression % expression) becomes XYZ

问题 In VB .Net it is possible to use inline If statements, like this if a Then ret = "A" Else ret = "Not A" I know it is also possible to nest these statements. I know this might not be good practice as readability drops down... If a Then If b Then ret = "A & B" Else ret = "A & Not B" Else ret = "Not A" which will be evaluated like this : If a Then If b Then ret = "A & B" Else ret = "A & Not B" End If Else ret = "Not A" End If Now if I remove the last Else statement, I get this : If a Then If b

问题 I am generating a tree (nested UL list) with javascript using the self-calling function below. I might add that it is within a jQuery plugin, if that is at all relevant to the issue (perhaps it might be?). The variable gd contains a json/array sniffed from a filestructure, so it's basically folders and images's names, and some more data (like the self-explainatory isFolder attribute etc.) for (i = 0; i < gd.length; ++i) { is interrupted by the self-call. var drawTree = function(self,parent){

问题 I have 52 json files (r$i.json) containing each 25 results (0 to 24). I'd like to create a json file with a special name for each of these results. The name would be composed according to the content of each of these results : YYYYMMDDHHMMSS_company_jobtitle.json the command generating names work fine : #!bin/bash for ((j=0;j<=24;j++)) do datein=$(jq <"r1.json" ".results[$j].date" | sed 's/"//g') dateout=$(date -d "${datein}" +"%Y%m%d%H%M%S") company=$(jq <"r1.json" ".results[$j].company" |

问题 I am trying to figure out how can we add additional information to python dictionary. For example as per standard way, we can have ["python":14, "Programming":15] . Now I may want to store it as ["d1":"python":14, "d1":"Programming":15] as 1 set. How can we achieve this? 回答1: store dicts of dicts using d1, d2,d3 etc.. as the keys: d={"d1":{"python":14,"Programming":15},"d2":{"python":14,"Programming":15}} Just access each sub dict to get what you need: In [11]: d = {"d1":{"python":14,
