課程 4（共 5 門，Specialization 零基础 Python 入门）

This course will introduce students to the basics of the Structured Query Language (SQL) as well as basic database design for storing data as part of a multi-step data gathering, analysis, and processing effort. The course will use SQLite3 as its database. We will also build web crawlers and multi-step data gathering and visualization processes. We will use the D3.js library to do basic data visualization. This course will cover Chapters 14-15 of the book “Python for Everybody”. To succeed in this course, you should be familiar with the material covered in Chapters 1-13 of the textbook and the first three courses in this specialization. This course covers Python 3.

與講師見面

Charles Severance
Professor
School of Information

Hi, Chuck here.

I'm in Zagreb, Croatia.

And here we are at another instance of an Office Hours.

The extended edition.

Tell us your name.

>> Hi, I'm Marco.

>> Tell me what are you doing in education right now?

What degree are you pursuing?

>> I'm studying faculty of electrical engineering and

computing at University of Zagreb, and I am graduate student.

>> And so how many Coursera classes have you taken?

>> I've taken two courses, yours and Introduction to Python.

>> Why do you use Coursera?

Why do you add in Coursera to you education?

>> Because first of all I want to broaden my knowledge.

>> And after all, some, how

do you say?

To show something in my CV that I

have taken other courses than studying at a faculty.

>> Do you have any suggestions for improvements?

Or what would you say if you were talking to the people who ran Coursera?

>> Just make it faster.

>> Make it faster?

>> Yeah.

>> Okay.

So, tell me your name.

>> My name is Anamaria Cudanar.

I'm student of philosophy and

social humanistic informatics, graduate and undergraduate.

What was the question?

[LAUGH] >> So

tell me about how many Coursera courses have you taken?

>> I've taken four, Guide to Irrational Behavior,

How to reason and argue, and human computer interaction.

And the fourth one was artificial intelligence at Stanford.

>> Did you finish them all?

>> No, I finished only one.

And I got a certificate from how to reason and argue.

So how do you fit it in with the rest of your education, I mean how does it fit,

and what part of your education does Coursera fulfill?

>> The things that I learned are outside of my study scope,

I'm really interesting in a lot of things and I think that people should be

more prone to interdisciplinary, >> So I want to learn things from other

places, and I think that makes me more valuable at the market,

and I'm really genuinely interested in a lot of things.

>> So is there anything that worries you about Coursera, does it bother you, or

do you have some fears about the future?

Or do you think it's like >> Fears?

I fear that it will become, when money gets involved,

it will no longer probably able to be open-source because somebody has to pay

it, and I think it's only a matter of time when it

will get, somebody will have to pay for it.

So, I'm afraid that it will no longer be available to a lot of people.

>> Okay. Do you have anything you would say,

to suggest to improve it?

That you're a professional and sort of learning technology.

Do you have any suggestions?

>> Just make it fun.

Like you or Don already does.

>> Okay.

>> Okay, so.

>> So there you have it, the voice of the student from downtown Zagreb,

and we'll talk to you next time.
