问题 I am trying to take a list of names, alphabetize them and print them to a new list. Here is my code: names = [] newnames = [] with open("C:/names.txt", "r") as infile: for row in infile.readlines(): name = row.split() names.append(name) for x in sorted(names): newnames.append(x) print newnames f = open("C:/newnames.txt", "w") f.write("\n".join(str(x) for x in newnames)) f.close() my problem is that it prints fine except for the brackets: ['Bradley'] ['Harold'] ['Jackson'] ['Lincoln'] [

If the box is

问题 Is there any performance difference between using Javascript function toUpperCase vs using CSS text-transform: uppercase ? To clarify, let's take the simplest case: <h1 id="greetings"></h1> <script> var name = "Nour" document.getElementById("greetings").innerHTML="Hello" + name.toUpperCase(); </script> rather than: <script> var name = "Nour" document.getElementById("greetings").innerHTML="Hello" + name; </script> <style> #greetings { text-transform:uppercase } </style> What's the performance

问题 I am trying to code a program that picks 3 random lines from a text file (that contains 50 lines) and outputs them to the screen. Here is my current code: string line; int random = 0; int numOfLines = 0; ifstream File("file.txt"); srand(time(0)); random = rand() % 50; while(getline(File, line)) { ++numOfLines; if(numOfLines == random) { cout << line; } } I can get it to print one random line like it does above but not three random lines. 回答1: What you should do depends on what exactly you

问题 I have two tables (equipment & software) that I want to do an INNER JOIN on. They both have a field called EQCN. It is a text field.

For this sample, only "apple firm" should stay. I tried to use the tm package, but it can only help me delete the non-english characters instead of the whole queries. 回答1: I would check out this related Stack Overflow post for doing the same thing in javascript. Regular expression to match non-English
