英文:
how print variable values in Go with fmt.Printl?
问题
我有以下代码片段：
x_variable := 12311fmt.Println("message", "X变量的值为'+x_variable+'，现在在屏幕上打印出来")
我该如何使其工作？
我在Go playground中尝试过，但无法正确打印出该值。
英文:
I have the below code snippet:
x_variable := 12311fmt.Println("message", "X variable has the value '+x_variable+' printed in the screen now")
How can I make that work?
I've tried that in the Go playground but couldn't figure it out how to print the vaue properly.

包 mainimport ("fmt")func main() {x_variable := 12311fmt.Printf("message X变量的值为 %d，现在在屏幕上打印出来", x_variable)}
英文:
package mainimport ("fmt")func main() {x_variable := 12311fmt.Printf("message X variable has the value %d printed in the screen now", x_variable)}</details># 答案2**得分**: -2你需要的是[Sprintf](https://pkg.go.dev/fmt#Sprintf)。你可以在那里找到一个[示例](https://go.dev/play/p/geqloT6q3_H)。由于你想打印一个整数，你可以使用`%d`修饰符。请记住，`Sprintf`系列函数不会自动插入换行符，所以你还需要使用`\n`。<details><summary>英文:</summary>What you need is [Sprintf](https://pkg.go.dev/fmt#Sprintf)You can find already an [example](https://go.dev/play/p/geqloT6q3_H) there.Since you want to print an integer, you can use the `%d` modifier.Keep in mind that `Sprintf` family does not insert newline automatically, so you will also need `\n`</details>
