如何将多个字符串和int合并为单个字符串

Question

我是Go的新手。 找不到任何官方文档显示如何将多个字符串合并为一个新字符串。

我所期望的是：

输入值: "key:", "value", ", key2:", 100

输出值: "Key:value, key2:100"

如果可能的话，我想使用+来合并字符串，就像在Java和Swift中一样。

I like to use fmt's Sprintf method for this type of thing. It works like normal Printf in Go or C only it returns a string. Here's an example;

output := fmt.Sprintf("%s%s%s%d", "key:", "value", ", key2:", 100)
