如何将时间格式转换为其他格式？

from datetime import datetime

# 将字符串转换为日期时间对象
date_str = "2023-10-05"
date_obj = datetime.strptime(date_str, "%Y-%m-%d")

# 将日期时间对象转换为其他格式
formatted_date = date_obj.strftime("%B %d, %Y")
print(formatted_date)  # 输出: October 05, 2023

# 将时间戳转换为日期时间对象
timestamp = 1696483200
date_from_timestamp = datetime.fromtimestamp(timestamp)
print(date_from_timestamp)  # 输出: 2023-10-05 00:00:00

// 将字符串转换为日期对象
let dateStr = "2023-10-05";
let dateObj = new Date(dateStr);

// 将日期对象转换为其他格式
let formattedDate = dateObj.toLocaleDateString("en-US", { year: "numeric", month: "long", day: "numeric" });
console.log(formattedDate);  // 输出: October 5, 2023

// 将时间戳转换为日期对象
let timestamp = 1696483200000;
let dateFromTimestamp = new Date(timestamp);
console.log(dateFromTimestamp);  // 输出: Thu Oct 05 2023 00:00:00 GMT+0000 (Coordinated Universal Time)
