将任意数字格式化为三位数？

number = 1234
formatted_number = "{:0>3}".format(number)
print(formatted_number)  # 输出：1234

int number = 1234;
String formattedNumber = String.format("%03d", number);
System.out.println(formattedNumber);  // 输出：1234

let number = 1234;
let formattedNumber = number.toLocaleString('en-US', {minimumIntegerDigits: 3, useGrouping:false});
console.log(formattedNumber);  // 输出：1234

int number = 1234;
string formattedNumber = number.ToString("D3");
Console.WriteLine(formattedNumber);  // 输出：1234

$number = 1234;
$formattedNumber = sprintf("%03d", $number);
echo $formattedNumber;  // 输出：1234
