计算机代写|Python作业代写|How Programming Is Different from Using a Computer
The first thing you need to understand about computers when you’re programming is that you control the computer. Sometimes the computer doesn’t do what you expect, but even when it doesn’t do what you want the first time, it should do the same thing the second and third time until you take charge and change the program.
The trend in personal computers has been away from reliability and toward software being built on top of other, unreliable, software. The results that you live with might have you believing that computers are malicious and arbitrary beasts, existing to taunt you with unbearable amounts of extra work and various harassments while you’re already trying to accomplish something. If you do feel this way, you already know that you’re not alone. However, after you’ve learned how to program, you gain an understanding of how this situation has come to pass, and perhaps you’ll find that you can do better than some of the programmers whose software you’ve used.
Note that programming in a language like Python, an interpreted language, means that you are not going to need to know a whole lot about computer hardware, memory, or long sequences of $0 \mathrm{~s}$ and $1 \mathrm{~s}$. You are going to write in text form like you are used to reading and writing but in a different and simpler language. Python is the language, and like English or any other language(s) you speak, it makes sense to other people who already speak the language. Learning a programming language can be even easier, however, because programming languages aren’t intended for discussions, debates, phone calls, plays, movies, or any kind of casual interaction. They’re intended for giving instructions and ensuring that those instructions are followed. Computers have been fashioned into incredibly flexible tools that have found a use in almost every business and task that people have found themselves doing, but they are still built from fundamentally understandable and controllable pieces.
Programming Is Consistency
In spite of the complexity involved in covering all of the disciplines into which computers have crept, the basic computer is still relatively simple in principle. The internal mechanisms that define how a computer works haven’t changed a lot since the 1950s when transistors were first used in computers.
In all that time, this core simplicity has meant that computers can, and should, be held to a high standard of consistency. What this means to you, as the programmer, is that anytime you tell a computer to metaphorically jump, you must tell it how high and where to land, and it will perform that jump – over and over again for as long as you specify. The program should not arbitrarily stop working or change how it works without you facilitating the change.
计算机代写|Python作业代写|Programming Is Control
Programming a computer is very different from creating a program, as the word applies to people in real life. In real life, we ask people to do things, and sometimes we have to struggle mightily to ensure that our wishes are carried out – for example, if we plan a party for 30 people and assign two of them to bring the chips and dip and two of them to bring the drinks.
With computers that problem doesn’t exist. The computer does exactly what you tell it to do. As you can imagine, this means that you must pay some attention to detail to ensure that the computer does just what you want it to do.
One of the goals of Python is to program in blocks that enable you to think about larger and larger projects by building each project as pieces that behave in well-understood ways. This is a key goal of a programming style known as object-oriented programming. The guiding principle of this style is that you can create reliable pieces that still work when you piece them together, that are understandable, and that are useful. This gives you, the programmer, control over how the parts of your programs run, while enabling you to extend your program as the problems you’re solving evolve.
Programming Copes with Change
Programs are run on computers that handle real-world problems; and in the real world, plans and circumstances frequently change. Because of these shifting circumstances, programmers rarely get the opportunity to create perfectly crafted, useful, and flexible programs. Usually, you can achieve only two of these goals. The changes that you will have to deal with should give you some perspective and lead you to program cautiously. With sufficient caution, you can create programs that know when they’re being asked to exceed their capabilities, and they can fail gracefully by notifying their users that they’ve stopped. In the best cases, you can create programs that explain what failed and why. Python offers especially useful features that enable you to describe what conditions may have occurred that prevented your program from working.
What All That Means Together
Taken together, these beginning principles mean that you’re going to be introduced to programming as a way of telling a computer what tasks you want it to do, in an environment where you are in control. You will be aware that sometimes accidents can happen and that these mistakes can be accommodated through mechanisms that offer you some discretion regarding how these conditions will be handled, including recovering from problems and continuing to work.
The First Steps
First, you should go online to the web site for the book, following the procedure in the Introduction, and follow the instructions there for downloading PythonCard. PythonCard is a set of utilities that provides an environment for programming in Python. PythonCard is a product that’s free to use and distribute and is tailor-made for writing in Python. It contains an editor, called codeEditor, that you will be using for the first part of this book. It has a lot in common with the editor that comes with Python, called idle, but in the opinion of the authors, codeEditor works better as a teaching tool because it was written with a focus on users who may be working on simpler projects. In addition, codeEditor is a program written in Python.
Python作业代写
计算机代写|Python作业代写|How Programming Is Different from Using a Computer
当你在编程时,你需要了解的第一件事是你控制着计算机。有时候,电脑并没有按照你的期望运行,但即使它第一次没有按照你的期望运行,它也应该在第二次和第三次运行同样的事情,直到你接管并改变程序。
个人电脑的发展趋势已经不再是可靠,而是将一个软件构建在另一个不可靠的软件之上。你生活的结果可能会让你相信电脑是恶意的、专横的野兽,当你已经在努力完成一些事情时,它会用无法忍受的额外工作和各种骚扰来嘲弄你。如果你确实有这种感觉,你已经知道你并不孤单。然而,在您学会了如何编程之后,您就会理解这种情况是如何发生的,也许您会发现您可以比使用过其软件的某些程序员做得更好。
请注意,使用Python这样的解释性语言进行编程意味着您不需要对计算机硬件、内存或$0 \mathrm{~s}$和$1 \mathrm{~s}$的长序列了解很多。你要用文本形式写,就像你习惯阅读和写作一样,但要用一种不同的、更简单的语言。Python是一门语言,就像英语或你说的任何其他语言一样,它对已经说这种语言的其他人来说是有意义的。然而,学习一门编程语言可能更容易,因为编程语言不是用于讨论、辩论、电话、戏剧、电影或任何类型的随意交互的。它们是用来给出指示并确保这些指示得到遵守的。计算机已经被塑造成令人难以置信的灵活工具,几乎在人们从事的所有业务和任务中都得到了应用,但它们仍然是由基本的可理解和可控的部分组成的。
编程就是一致性
尽管涵盖计算机所涉及的所有学科都很复杂,但基本计算机在原理上仍然相对简单。自20世纪50年代晶体管首次用于计算机以来,定义计算机工作方式的内部机制并没有发生太大变化。
一直以来,这种核心的简单性意味着计算机可以,也应该保持高度的一致性。作为程序员,这对你来说意味着,任何时候你让计算机跳起来,你必须告诉它要跳多高,在哪里降落,它会一次又一次地跳下去,只要你指定。程序不应该任意停止工作或改变它的工作方式,而没有您的帮助。
计算机代写|Python作业代写|Programming Is Control
为计算机编程与创建程序非常不同,因为这两个词适用于现实生活中的人。在现实生活中,我们要求别人做一些事情,有时我们必须努力确保我们的愿望得到实现——例如,如果我们计划一个30人的聚会,指定其中两个人带薯条和蘸酱,另两个人带饮料。
有了电脑,这个问题就不存在了。电脑完全按照你的吩咐去做。你可以想象,这意味着你必须注意一些细节,以确保计算机做你想让它做的事情。
Python的目标之一是用块编程,通过将每个项目构建为以易于理解的方式运行的块,使您能够考虑越来越大的项目。这是称为面向对象编程的编程风格的关键目标。这种风格的指导原则是,您可以创建可靠的部分,这些部分在您将它们拼接在一起时仍然可以工作,并且是可以理解的,并且是有用的。这使程序员能够控制程序各部分的运行方式,同时使您能够随着正在解决的问题的发展而扩展程序。
编程应对变化
程序在处理现实问题的计算机上运行;在现实世界中,计划和环境经常变化。由于这些变化的环境,程序员很少有机会创建完美的、有用的和灵活的程序。通常,您只能实现其中两个目标。您必须处理的更改应该给您一些视角,并引导您谨慎地进行编程。只要足够小心,您就可以创建这样的程序:它们知道何时被要求超出它们的能力,并且它们可以通过通知用户它们已经停止而优雅地失败。在最好的情况下,您可以创建程序来解释失败的原因和原因。Python提供了特别有用的特性,使您能够描述可能发生的阻止程序工作的条件。
这意味着什么
总的来说,这些基本原则意味着你将被介绍到编程,作为一种在你控制的环境中告诉计算机你想让它做什么任务的方式。您将意识到,有时可能会发生事故,这些错误可以通过机制来调节,这些机制为您提供了一些关于如何处理这些情况的自由裁量权,包括从问题中恢复并继续工作。
第一步
首先,您应该在线访问本书的网站,按照介绍中的步骤,并按照那里的说明下载PythonCard。PythonCard是一组实用程序,为Python编程提供了一个环境。PythonCard是一个免费使用和分发的产品,是为用Python编写而定制的。它包含一个名为codeEditor的编辑器,您将在本书的第一部分中使用它。它与Python附带的编辑器有很多共同之处,称为idle,但在作者看来,codeEditor作为教学工具更好,因为它是针对那些可能从事更简单项目的用户编写的。此外,codeEditor是一个用Python编写的程序。

线性代数代写
线性代数是数学的一个分支,涉及线性方程,如:线性图,如:以及它们在向量空间和通过矩阵的表示。线性代数是几乎所有数学领域的核心。
博弈论代写
现代博弈论始于约翰-冯-诺伊曼(John von Neumann)提出的两人零和博弈中的混合策略均衡的观点及其证明。冯-诺依曼的原始证明使用了关于连续映射到紧凑凸集的布劳威尔定点定理,这成为博弈论和数学经济学的标准方法。在他的论文之后,1944年,他与奥斯卡-莫根斯特恩(Oskar Morgenstern)共同撰写了《游戏和经济行为理论》一书,该书考虑了几个参与者的合作游戏。这本书的第二版提供了预期效用的公理理论,使数理统计学家和经济学家能够处理不确定性下的决策。
微积分代写
微积分,最初被称为无穷小微积分或 “无穷小的微积分”,是对连续变化的数学研究,就像几何学是对形状的研究,而代数是对算术运算的概括研究一样。
它有两个主要分支,微分和积分;微分涉及瞬时变化率和曲线的斜率,而积分涉及数量的累积,以及曲线下或曲线之间的面积。这两个分支通过微积分的基本定理相互联系,它们利用了无限序列和无限级数收敛到一个明确定义的极限的基本概念 。
计量经济学代写
什么是计量经济学?
计量经济学是统计学和数学模型的定量应用,使用数据来发展理论或测试经济学中的现有假设,并根据历史数据预测未来趋势。它对现实世界的数据进行统计试验,然后将结果与被测试的理论进行比较和对比。
根据你是对测试现有理论感兴趣,还是对利用现有数据在这些观察的基础上提出新的假设感兴趣,计量经济学可以细分为两大类:理论和应用。那些经常从事这种实践的人通常被称为计量经济学家。
Matlab代写
MATLAB 是一种用于技术计算的高性能语言。它将计算、可视化和编程集成在一个易于使用的环境中,其中问题和解决方案以熟悉的数学符号表示。典型用途包括:数学和计算算法开发建模、仿真和原型制作数据分析、探索和可视化科学和工程图形应用程序开发,包括图形用户界面构建MATLAB 是一个交互式系统,其基本数据元素是一个不需要维度的数组。这使您可以解决许多技术计算问题,尤其是那些具有矩阵和向量公式的问题,而只需用 C 或 Fortran 等标量非交互式语言编写程序所需的时间的一小部分。MATLAB 名称代表矩阵实验室。MATLAB 最初的编写目的是提供对由 LINPACK 和 EISPACK 项目开发的矩阵软件的轻松访问,这两个项目共同代表了矩阵计算软件的最新技术。MATLAB 经过多年的发展,得到了许多用户的投入。在大学环境中,它是数学、工程和科学入门和高级课程的标准教学工具。在工业领域,MATLAB 是高效研究、开发和分析的首选工具。MATLAB 具有一系列称为工具箱的特定于应用程序的解决方案。对于大多数 MATLAB 用户来说非常重要,工具箱允许您学习和应用专业技术。工具箱是 MATLAB 函数(M 文件)的综合集合,可扩展 MATLAB 环境以解决特定类别的问题。可用工具箱的领域包括信号处理、控制系统、神经网络、模糊逻辑、小波、仿真等。
