如何解决“太多争论返回”问题在Golang？ [英] How to solve "too many arguments to return" issue in Golang?

问题描述

在我写的打印函数中，我试图根据switch语句的结果返回一个值;然而，我得到的错误太多的参数返回。

原谅我，如果这个问题有一个简单的答案，但不应该有多少参数一个函数有，它只能返回一件事？或者它需要为每个参数返回一件事情。

这是我的代码。我在返回行出现错误（返回的参数过多）。如何修复它，以便它返回在switch语句中设置的字符串？

 包托架
 
 func打印（DATA [] TD，包含字符串，排除[]字符串，字符串）{
结果：= NBC（DATA，包含，排除，str）
 var发送字符串
开关结果{
案例1：
 sentAnal =强烈否定
案例2：
 sentAnal =非常消极
案例3：
 sentAnal =负数
案例4：
 sentAnal =小负数
案例5：
 sentAnal =Neurtral
案例6：
 sentAnal =小正面
案例7：
 sentAnal =正面
案例8：
 sentAnal =更积极
案例9：
 sentAnal =非常正面
案例10：
 sentAnal =强烈正面
默认值：
 sentAnal =未知
} 
返回sentAnal 
} 
  

解决方案

您需要在指定输入参数后指定要返回的内容，这不是python。

  func打印（DATA [] TD，包括字符串，排除[]字符串，字符串）{
  code> 

应该是：



  func Print（DATA [] TD，包括字符串，排除[]字符串，字符串）字符串{

In a print function I am writing, I am trying to return a value based on the result of a switch statement; however, I am getting the error too many arguments to return.

Forgive me if this question has a simple answer, but shouldn't it not matter how many arguments a function has and it can return just one thing? Or does it need to return one thing for each argument.

Here is my code. I am getting an error on the return line ( Too many arguments to return ). How can I fix it so that it returns the string set in the switch statement?

package bay

func Print(DATA []TD, include string, exclude []string, str string) {
    result := NBC(DATA, include, exclude, str)
    var sentAnal string
    switch result {
    case 1:
        sentAnal = "Strongly Negative"
    case 2:
        sentAnal = "Very Negative"
    case 3:
        sentAnal = "Negative"
    case 4:
        sentAnal = "Little Negative"
    case 5:
        sentAnal = "Neurtral"
    case 6:
        sentAnal = "Little Positive"
    case 7:
        sentAnal = "Positive"
    case 8:
        sentAnal = "More Positive"
    case 9:
        sentAnal = "Very Positive"
    case 10:
        sentAnal = "Strongly Positive"
    default:
        sentAnal = "Unknown"
    }
    return sentAnal
}

解决方案

You need to specify what you will return after specifying the input parameters, this is not python.

This:

func Print(DATA []TD, include string, exclude []string, str string) {

Should be:

func Print(DATA []TD, include string, exclude []string, str string) string {
