问题 Here are the steps I'm following to do a Multinomial Linear Regression. > z<-read.table("2008 Racedata.txt", header=TRUE, sep="\t", row.names=NULL) > head(z) datekey raceno horseno place winner draw winodds log_odds jwt hwt 1 2008091501 1 8 1 1 2 12.0 2.484907 128 1170 2 2008091501 1 11 2 0 3 8.6 2.151762 123 1135 3 2008091501 1 6 3 0 5 7.0 1.945910 127 1114 4 2008091501 1 12 4 0 10 23.0 3.135494 123 1018 5 2008091501 1 14 5 0 4 11.0 2.397895 113 1027 6 2008091501 1 5 6 0 14 50.0 3.912023 131

问题 So I'm working on cleanup of a horrible codebase, and I'm slowly moving to full error reporting. It's an arduous process, with hundreds of notices along the lines of: Notice: Undefined index: incoming in /path/to/code/somescript.php on line 18 due to uses of variables assuming undefined variables will just process as false, like: if($_SESSION['incoming']){ // do something } The goal is to be able to know when a incorrectly undefined variable introduced, the ability to use strict error/notice

问题 Before I start, no I have no issues that I can find with semicolons, and I'm passing NO values to the function. When I try to do function "login()" from the console, it works just fine, but when I click an HTML input button to call it, I get "Uncaught TypeError: object is not a function". This is in Chrome by the way. var aj=new XMLHttpRequest(); var loginf=document.forms["login"]; var regf=document.forms["reg"]; function login(){ var errors=document.getElementById("login_err"); var errs=[];

Here is my full error: Parse error: syntax error, unexpected T_VARIABLE in C:\xampp\htdocs\GigaLoad

问题 I have tried creating the following function: def 3utr(): do_something() . However, I get a SyntaxError. Replacing the "3" by "three" fixes the problem. My questions are: Why is it a syntax error? Is there a way to have a function name start with a number in Python 3? 回答1: It is a syntax error because the language specification does not allow identifiers to start with a digit. So it’s not possible to have function names (which are identifiers) that start with digits in Python. identifier ::=

问题 Everyone runs into syntax errors. Even experienced programmers make typos. For newcomers, it's just part of the learning process. However, it's often easy to interpret error messages such as: PHP Parse error: syntax error, unexpected '{' in index.php on line 20 The unexpected symbol isn't always the real culprit. But the line number gives a rough idea of where to start looking. Always look at the code context . The syntax mistake often hides in the mentioned or in previous code lines .

问题 I am writing some classes using Generics but I can't find a solution for the class SolutionsSubset and so I a getting the error "type parameter S is not within its bound". I have read previous questions about the same error but I can't solve it for my case. Could anybody help me to improve my knowledge about generics? Any reference to a good book (I can find in google a lot of information but if someone can reccommend a book, tutorial, etc. will be welcome). Although I tried to keep in mind

问题 The error message I got: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''word','group','selfnote') VALUES ('item','a','note to self')' at line 1 The PHP code is: $toq="INSERT INTO articles ('word','group','selfnote') VALUES ('$ttle','$wrdr','$snote')"; I was trying to find solutins, but they didn't seem to work as echoing gives: INSERT INTO articles ('word','group','selfnote') VALUES ('item','a','note to
