如何格式化日期YYYYMMDDmmhhssuuu

from datetime import datetime

# 当前时间
now = datetime.now()

# 格式化为 YYYYMMDDmmhhssuuu
formatted_date = now.strftime('%Y%m%d%H%M%S%f')
print(formatted_date)

// 当前时间
const now = new Date();

// 格式化为 YYYYMMDDmmhhssuuu
const formattedDate = `${now.getFullYear()}${String(now.getMonth() + 1).padStart(2, '0')}${String(now.getDate()).padStart(2, '0')}${String(now.getHours()).padStart(2, '0')}${String(now.getMinutes()).padStart(2, '0')}${String(now.getSeconds()).padStart(2, '0')}${String(now.getMilliseconds()).padStart(3, '0')}`;
console.log(formattedDate);

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class DateFormatExample {
    public static void main(String[] args) {
        // 当前时间
        LocalDateTime now = LocalDateTime.now();

        // 格式化为 YYYYMMDDmmhhssuuu
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMddHHmmssSSS");
        String formattedDate = now.format(formatter);
        System.out.println(formattedDate);
    }
}
