如何在python中将日期时间转换为unix时间戳？

import datetime

def datetime_to_timestamp(dt):
    epoch = datetime.datetime.utcfromtimestamp(0)
    delta = dt - epoch
    return delta.total_seconds()

# 获取当前日期时间
current_datetime = datetime.datetime.now()

# 将日期时间转换为Unix时间戳
timestamp = datetime_to_timestamp(current_datetime)

print("当前日期时间：", current_datetime)
print("Unix时间戳：", timestamp)
