This course aims to teach everyone the basics of programming computers using Python. We cover the basics of how one constructs a program from a series of simple instructions in Python. The course has no pre-requisites and avoids all but the simplest mathematics. Anyone with moderate computer experience should be able to master the materials in this course. This course will cover Chapters 1-5 of the textbook “Python for Everybody”. Once a student completes this course, they will be ready to take more advanced programming courses. This course covers Python 3.

课程大纲

周1
完成时间为 2 小时
Chapter One - Why we Program?
These are the course-wide materials as well as the first part of Chapter One where we explore what it means to write programs. We finish Chapter One and have the quiz and first assignment in the third week of the class. Throughout the course you may want to come back and look at these materials. This section should not take you an entire week.
6 个视频（总计 38 分钟）, 6 个阅读材料

周2
完成时间为 4 小时
Installing and Using Python
In this module you will set things up so you can write Python programs. Not all activities in this module are required for this class so please
read the "Using Python in this Class" material for details.

周3
完成时间为 2 小时
Chapter One: Why We Program (continued)
In the first chapter we try to cover the "big picture" of programming so you get a "table of contents" of the rest of the book. Don't worry if not everything makes perfect sense the first time you hear it. This chapter is quite broad and you would benefit from reading the chapter in the book in addition to watching the lectures to help it all sink in. You might want to come back and re-watch these lectures after you have funished a few more chapters.

周4
完成时间为 3 小时
Chapter Two: Variables and Expressions
In this chapter we cover how a program uses the computer's memory to store, retrieve and calculate information.
6 个视频（总计 56 分钟）, 1 个阅读材料, 3 个测验

周5
完成时间为 3 小时
Chapter Three: Conditional Code
In this section we move from sequential code that simply runs one line of code after another to conditional code where some steps are
skipped. It is a very simple concept - but it is how computer software makes "choices".

周6
完成时间为 2 小时
Chapter Four: Functions
This is a relatively short chapter. We will learn about what functions are and how we can use them. The programs in the first chapters of the book are not large enough to require us to develop functions, but as the book moves into more and more complex programs, functions will be an essential way for us to make sense of our code.
4 个视频（总计 35 分钟）, 2 个测验

周7
完成时间为 3 小时
Chapter Five: Loops and Iteration
Loops and iteration complete our four basic programming patterns. Loops are the way we tell Python to do something over and over. Loops
are the way we build programs that stay with a problem until the problem is solved.

预备知识

无需预备知识。内容不涉及高等数学，全部课程都可以使用网页浏览器完成。如果用个人电脑完成编程作业（选作），要知道如何下载和安装软件，能在电脑上建立文件夹和整理文件。我们为使用个人电脑（Windows和Macintosh）学习软件开发的学生提供了详细的教学视频，内容包括所有软件安装和文件管理任务。课上所有必用软件全部免费。
