string.format
是一个用于格式化字符串的方法,它在许多编程语言中都有类似的实现。以下是一些常见编程语言中 string.format
的实现:
- Python:
formatted_string = "Hello, {}! Your age is {}.".format("Alice", 30)
- Java:
String formattedString = String.format("Hello, %s! Your age is %d.", "Alice", 30);
- C#:
string formattedString = string.Format("Hello, {0}! Your age is {1}.", "Alice", 30);
- JavaScript:
let formattedString = `Hello, ${'Alice'}! Your age is ${30}.`;
- Ruby:
formatted_string = "Hello, #{Alice}! Your age is #{30}."
- PHP:
$formatted_string = "Hello, %s! Your age is %d."; echo sprintf($formatted_string, "Alice", 30);
- Swift:
let formattedString = "Hello, \(Alice)! Your age is \(30)."
请注意,这些示例中的语法可能略有不同,但它们都实现了类似的功能,即使用占位符替换字符串中的变量值。
