@Jimmy Wong have you try restarting the notebook? i.e. Menu -> Kernel -> Restart

then try install cufflinks :)

@willykwok If you still want a interactive plot, you can try the following: import pandas as pd import plotly import cufflinks as cf cf.go_offline() df = pd.DataFrame([1,2,5]) fig = df.iplot(kind="line", asFigure=True) plotly.offline.plot(fig, filename="tmp.html") It will not show in terminal, but It will open in a browser also a tmp.html will be made at the current dir

The interactive plot cannot show up in a terminal. You may want to use matplotlib to make a static picture instead eg: https://pythonspot.com/matplotlib-save-figure-to-image-file/

nice, that's one of the possible correct ways to do the job

put it another way if you clear and rerun the notebook (Menu -> Kernel Restart and run all) what is the len and content of r before the for loop?

you have fill in stuff in the for loop but how is r created at first?

it seems you have duplicated things 5 times 7375/1475 = 5 but i cannot see how you define r in the screen shot. what is the code above this cell?

hint: after s=s.upper try to add this line print(s) is it what you expect? hint2: what is the difference between s.upper and s.upper()

Hello, this has a few steps, but just follow one by one and you should be able to run it :) 1. Open anaconda prompt, type the following and <Enter> pip install dash colorlover 2. Then remember it is a .py file? We can run it with anaconda prompt/ VS code, Here I show the VS code way: Open the folder "dash-stock-tickers-demo-app-master" with VS code 3. double click app.py then run it with F5 4. After a few seconds, it will output "Runnnig on http://??????????", Ctrl+Click it, and you will see the plot opened on a browser. 5. Final result :)

Fist click open folder Choose "Guess Age", Then click "Select Folder" You should then see Guess Age. py You can double click to open it, and F5 to run it
