دوره Programming for Everybody (Getting Started with Python) ، فصل 3 : Chapter One- Why We Program (continued)
دربارهی این فصل:
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.
این دوره شامل 4 فصل زیر است:
And I see students all the time, they try to write whole programs in that and it gets a little frustrating because you have to type it perfectly from beginning to end. And so you'll see, it starts at the beginning and the if has embedded in it a question that leads to a true or a false, ends in a colon, and then there's an indented block. Print smaller is the conditional statement, meaning that if x is less than 10 evaluates to true, then it's going to execute; otherwise, it's going to be skipped.
Now, the idea that I have is that you will actually write the Python on your computer using a real text editor like Atom, and then just paste the code in here to get graded, but we understand that if you're using an iPad or something else like that that this might be the only way that you're going to do it, or if you're in a school or something and they've only got Chromebooks, it's okay, you can do it. And if you don't see that, then you got a problem, or you can go back and check it in Coursera, but that is the moment where it's decided that you've done a good job. And so, that's basically the idea, let me finish this and get it back correct again, so I print out the right output.
And then in parallel to that, my colleague and co-founder Andrew Ng was actually working on a different trajectory, which is let's teach the world, and ended up developing pieces of the design and technology and pedagogy independently in the context of this other project. And at some point we realized that the projects were remarkably well aligned because the same ideas, the same designs, the same contents could be used for both improving the quality of the instruction for our on-campus students and for offering a meaningful course experience for the world. So, what happened was in I think August is when the decision was made, and we realized that the platforms that we had been using inside Stanford were just not up to the task of being available, robustly, to hundreds of thousands of students.
When I'm writing an operating system, I'm saying, oh here's this problem I've gotta solve, and here's these specifications in performance. So after that brief interruption by the construction crew, we'll go back to talking to Mauro, our intrepid community teaching assistant. And let's give Mauro a nice round of applause, thanking him for how awesome he is for doing what he does.
