Life was like a box of chocolates

本文通过一个生动的比喻,将生活比作同时抛接五个球的游戏,这五个球分别是工作、家庭、健康、朋友和精神。文章强调了这五个方面的重要性,并指出除了工作外,其余四个球都是易碎的玻璃球,一旦掉落就会受到不可逆的损伤。文章进一步阐述了如何在生活中寻找平衡的方法,包括不要拿自己和别人比较、珍惜身边的人和事等。

Imagine life as a game in which you are juggling some five balls in the air. You name them-work, family, health, friends, and spirit, and you're keeping all of t hese in the air. You will soon understand that work is a rubber ball. If you drop it, it will bounce back.

But the other four balls: family, health, friends and spirit are made of glass.

If you drop one of these, they will be irrevocably scuffed, marked, nicked, damag ed or even shattered. They will never be the same.

You must understand that and strive for balance in your life. How? Don't undermine your worth by comparing yourself with others. It is because we are different that each of us is special.

Don't set your goals by what other people deem important. Only you know what is best for you. Don't take for granted the things closest to your heart. Cling to them as you would your life, for without them, life is meaningless.

Don't let your life slip through your fingers by living in the past or for the f uture. By living your life one day at a time, you live ALL the days of your life.

Don't give up when you still have something to give. Nothing is really over until the moment you stop trying.

Don't be afraid to admit that you are less than perfect. It is this fragile thre ad that binds us to each together. Don't be afraid to encounter risks. It is by t aking chances that we learn how to be brave.

Don't shut love out of your life by saying it's impossible to find. The quickest way to receive love is to give it. The fastest way to lose love is to hold it to o tightly. The best way to keep love is to give it wings. Don't forget that a per son's greatest emotional need is to feel appreciated.

Don't run through life so fast that you forget not only where you've been, but a lso where you are going. Don't be afraid to learn. Knowledge is weightless, a tre asure you can always carry easily. Don't use time or words carelessly. Neither ca n be retrieved.

Life is not a race, but a journey to be savored each step of the way. Yesterday is History, Tomorrow is a Mystery, and Today is a gift: That's why we call it - The Present.

【无人机】基于改进粒子群算法的无人机路径规划研究[和遗传算法、粒子群算法进行比较](Matlab代码实现)内容概要:本文围绕基于改进粒子群算法的无人机路径规划展开研究,重点探讨了在复杂环境中利用改进粒子群算法(PSO)实现无人机三维路径规划的方法,并将其与遗传算法(GA)、标准粒子群算法等传统优化算法进行对比分析。研究内容涵盖路径规划的多目标优化、避障策略、航路点约束以及算法收敛性和寻优能力的评估,所有实验均通过Matlab代码实现,提供了完整的仿真验证流程。文章还提到了多种智能优化算法在无人机路径规划中的应用比较,突出了改进PSO在收敛速度和全局寻优方面的优势。; 适合人群:具备一定Matlab编程基础和优化算法知识的研究生、科研人员及从事无人机路径规划、智能优化算法研究的相关技术人员。; 使用场景及目标:①用于无人机在复杂地形或动态环境下的三维路径规划仿真研究;②比较不同智能优化算法(如PSO、GA、蚁群算法、RRT等)在路径规划中的性能差异;③为多目标优化问题提供算法选型和改进思路。; 阅读建议:建议读者结合文中提供的Matlab代码进行实践操作,重点关注算法的参数设置、适应度函数设计及路径约束处理方式,同时可参考文中提到的多种算法对比思路,拓展到其他智能优化算法的研究与改进中。
要实现程序功能:查找与特定词列表相匹配的字符串,并将其替换为 `*`,我们可以使用 Python 的字符串操作或正则表达式来完成。 下面是一个完整的 Python 程序示例,实现了该功能,并在关键位置标注了需要补充语句的“横线处”: ```python # 特定关键词列表 keywords = ['Life', 'chocolates', 'get'] # 输入字符串 text = input("请输入一段文本:") # 比如: Life is like a box of chocolates, you never know what you're gonna get. # 在横线处补充语句:对每个关键词进行替换 for word in keywords: text = text.replace(word, '*') # 补充语句 # 输出最终结果 print(text) ``` ### 解释: - `keywords` 是我们要查找并替换的关键词列表。 - 使用 `input()` 获取用户输入的字符串。 - **关键逻辑**:通过 `for` 循环遍历每一个关键词,使用字符串的 `.replace(old, new)` 方法将原文中所有匹配的词替换为 `'*'`。 - 注意:`.replace()` 是区分大小写的,所以 `'Life'` 能匹配开头大写的 Life,但不会匹配 life。如果希望不区分大小写,可以使用正则表达式。 --- ### 更健壮的版本(支持不区分大小写): ```python import re # 特定关键词列表 keywords = ['Life', 'chocolates', 'get'] # 输入字符串 text = input("请输入一段文本:") # 在横线处补充语句:使用正则表达式进行不区分大小写的替换 for word in keywords: # 使用 re.escape 防止特殊字符干扰,re.IGNORECASE 实现忽略大小写 text = re.sub(re.escape(word), '*', text, flags=re.IGNORECASE) # 补充语句 print(text) ``` #### 示例运行: **输入:** ``` Life is like a box of chocolates, you never know what you're gonna get. ``` **输出:** ``` * is like a box of *, you never know what you're gonna *. ``` ### 说明: - `re.sub(pattern, replacement, string, flags=re.IGNORECASE)` 可以进行更灵活的替换。 - `re.escape(word)` 确保像 `*`, `?` 这样的特殊字符不会引起正则错误(虽然本例中没有)。 - `flags=re.IGNORECASE` 让匹配不区分大小写,比如 "GET" 或 "Get" 也能被替换成 `*`。 --- ### 如果题目中的“横线处”指的是某一行缺失代码,常见的填空题形式如下: 假设原题结构如下: ```python keywords = ['Life', 'chocolates', 'get'] text = input() for word in keywords: ________________ # 横线处填空 print(text) ``` ✅ 正确答案应填写: ```python text = text.replace(word, '*') ``` 或者更高级地使用正则(若允许导入模块): ```python import re ... text = re.sub(re.escape(word), '*', text, flags=re.IGNORECASE) ``` ---
