string.format 是一個(gè)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(shí)現(xiàn)。以下是一些常見編程語言中 string.format 的實(shí)現(xiàn):

  1. Python:
formatted_string = "Hello, {}! Your age is {}.".format("Alice", 30)
  1. Java:
String formattedString = String.format("Hello, %s! Your age is %d.", "Alice", 30);
  1. C#:
string formattedString = string.Format("Hello, {0}! Your age is {1}.", "Alice", 30);
  1. JavaScript:
let formattedString = `Hello, ${'Alice'}! Your age is ${30}.`;
  1. Ruby:
formatted_string = "Hello, #{Alice}! Your age is #{30}."
  1. PHP:
$formatted_string = "Hello, %s! Your age is %d.";
echo sprintf($formatted_string, "Alice", 30);
  1. Swift:
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(shí)現(xiàn)了類似的功能,即使用占位符替換字符串中的變量值。
