如何将任何类型的日期转换为dd/mm/yyyy

from datetime import datetime

def convert_date(date_string, input_format):
    date_obj = datetime.strptime(date_string, input_format)
    return date_obj.strftime("%d/%m/%Y")

date_string = "2022-01-01"
input_format = "%Y-%m-%d"

converted_date = convert_date(date_string, input_format)
print(converted_date)

function convertDate(dateString, inputFormat) {
    const dateObj = new Date(dateString);
    const day = dateObj.getDate().toString().padStart(2, "0");
    const month = (dateObj.getMonth() + 1).toString().padStart(2, "0");
    const year = dateObj.getFullYear();
    return `${day}/${month}/${year}`;
}

const dateString = "2022-01-01";
const inputFormat = "YYYY-MM-DD";

const convertedDate = convertDate(dateString, inputFormat);
console.log(convertedDate);

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DateConverter {
    public static void main(String[] args) {
        String dateString = "2022-01-01";
        String inputFormat = "yyyy-MM-dd";
        String outputFormat = "dd/MM/yyyy";

        try {
            SimpleDateFormat inputFormatObj = new SimpleDateFormat(inputFormat);
            SimpleDateFormat outputFormatObj = new SimpleDateFormat(outputFormat);
            Date dateObj = inputFormatObj.parse(dateString);
            String convertedDate = outputFormatObj.format(dateObj);
            System.out.println(convertedDate);
        } catch (ParseException e) {
            e.printStackTrace();
        }
    }
}
