"meeting": 20.1,
})
fmt.Println("列表输出如下：\n" + s)
Output: name Joshua Conero meeting 20.1
func FormatList ¶
Example ¶
s := FormatList([]string{"1", "this\\'s test", "box", "a", "must", "base", "念奴娇", "√√√√√", "", "saw", "no-list", "box",
"box", "box", "box", "box", "box", "box", "box", "box", "box", "box", "box", "box", "box"})
