输入总金额和红包个数，如何生成一个随机金额的红包？

为了生成一个随机金额的红包，通常的做法是在给定的总金额和红包个数的前提下，对每个红包分配一个随机数值，确保这些数值之和等于总金额。以下是Python的一个简单示例：

import random

def generate_random_red_packet(total_amount, num_packages):
    # 确保红包总额不会超过总金额
    if total_amount < num_packages:
        raise ValueError("总金额不足以支付红包个数")

    remaining_amount = total_amount
    red_packets = []

    for _ in range(num_packages):
        # 随机取值范围为 [0, 剩余金额)
        random_amount = random.randint(1, remaining_amount)
        red_packets.append(random_amount)
        remaining_amount -= random_amount

    return red_packets

# 示例：
total_amount = 100
num_packages = 5
red_packet_distribution = generate_random_red_packet(total_amount, num_packages)

print(f"随机红包分配结果：{red_packet_distribution}")
