In Golang, fmt.Sprintf is a common function used to format strings. While it offers flexibility, there are scenarios where it can encounter unexpected behavior.
One such scenario is when a program passes a complete string without placeholders to fmt.Sprintf. Consider the following example:
<code class="go">import "fmt" func main() { tmp_str := "hello %s" str := fmt.Sprintf(tmp_str, "world") fmt.Println(str) }</code>
If the program receives a complete string like "Hello Friends" instead of a template, it will cause a panic and output an error message.
To mitigate this issue, several approaches can be considered:
Hello Friends%.0s
This will result in a plain output:
Hello Friends
