string.format 是一個用于格式化字符串的方法，它在許多編程語言中都有類似的實現。以下是一些常見編程語言中 string.format 的實現：
formatted_string = "Hello, {}! Your age is {}.".format("Alice", 30)
String formattedString = String.format("Hello, %s! Your age is %d.", "Alice", 30);
string formattedString = string.Format("Hello, {0}! Your age is {1}.", "Alice", 30);
let formattedString = `Hello, ${'Alice'}! Your age is ${30}.`;
formatted_string = "Hello, #{Alice}! Your age is #{30}."
$formatted_string = "Hello, %s! Your age is %d.";
echo sprintf($formatted_string, "Alice", 30);
let formattedString = "Hello, \(Alice)! Your age is \(30)."
請注意，這些示例中的語法可能略有不同，但它們都實現了類似的功能，即使用占位符替換字符串中的變量值。
