运算符不存在:整数+间隔

from datetime import datetime, timedelta

# 示例：将整数与时间间隔相加
date = datetime(2023, 10, 1)
days_to_add = 5
new_date = date + timedelta(days=days_to_add)
print(new_date)  # 输出: 2023-10-06 00:00:00

// 示例：将整数与时间间隔相加
let date = new Date('2023-10-01');
let daysToAdd = 5;
date.setDate(date.getDate() + daysToAdd);
console.log(date);  // 输出: 2023-10-06T00:00:00.000Z

import java.time.LocalDate;

// 示例：将整数与时间间隔相加
LocalDate date = LocalDate.of(2023, 10, 1);
int daysToAdd = 5;
LocalDate newDate = date.plusDays(daysToAdd);
System.out.println(newDate);  // 输出: 2023-10-06
