如何获取两个日期范围之间的天数

from datetime import datetime

def get_days_between_dates(start_date, end_date):
    start = datetime.strptime(start_date, "%Y-%m-%d")
    end = datetime.strptime(end_date, "%Y-%m-%d")
    delta = end - start
    return delta.days

start_date = "2022-01-01"
end_date = "2022-01-10"
days = get_days_between_dates(start_date, end_date)
print(days)

import java.time.LocalDate;
import java.time.temporal.ChronoUnit;

public class Main {
    public static void main(String[] args) {
        String startDate = "2022-01-01";
        String endDate = "2022-01-10";
        
        LocalDate start = LocalDate.parse(startDate);
        LocalDate end = LocalDate.parse(endDate);
        
        long days = ChronoUnit.DAYS.between(start, end);
        System.out.println(days);
    }
}

function getDaysBetweenDates(startDate, endDate) {
    const start = new Date(startDate);
    const end = new Date(endDate);
    const millisecondsPerDay = 24 * 60 * 60 * 1000;
    const days = Math.round(Math.abs((end - start) / millisecondsPerDay));
    return days;
}

const startDate = "2022-01-01";
const endDate = "2022-01-10";
const days = getDaysBetweenDates(startDate, endDate);
console.log(days);
