Here are three quick feedback for Week 9 notes:

For setting up the font part, the command "!open" doesn't work on my computer. I think it is because of the Window system. But we could try the command "matplotlib.get_cachedir()" , and it works.
I don't know why when I set the color, it sometimes raises such ValueError:
When I executed the plotly, it will return with errors like this...

Thanks a lot if you can help me solve!

thanks. about question 2, where did it go wrong? and about question 3, I'm not sure what's happening here @hupili do you know this problem?

country_counts = df['country'].value_counts()[:15].sort_values(ascending=False) country = pd.DataFrame(country_counts) fig = plt.figure(figsize=(14,7)) plt.bar(country.index, country.country,color = '#46c99',edgecolor = '#40b4e5')

But actually when I tried your codes, it works... So I have no idea why it raised a ValueError.

For the first question, I don't think there's such a command !open in Note09. Did you mean '!pip install' or open() ?

rippleYJH commented 5 years ago

I think it is open()

For question 2, since this is a HEXcolor, we can only set the code from #000000 to #ffffff.
For question 3, we can click into the URL to register and follow the instructions, then the library will work.

update the plotly offline method, which does not require an account. please see here.
