This dataframe appears to have correct maximum values, yet the COVID 19 project indicates that the solution is incorrect.

import pandas as pd
data = pd.read_csv("/usercode/files/ca-covid.csv")
df = pd.DataFrame(data)
df = df.assign(ratio = df.deaths/df.cases)
result = (df.sort_values(by=['ratio'],ascending=False))
del result ["state"]
result.set_index("date", inplace=True)
print (result.head(1))

Bob_Li Incredibly a direct copy paste worked 🐸 Bravo 🙏🏾

the output should be a dataframe...
The code coach also seems questionable...I had to drop the 'state' column in order to pass, but it was not explicitly stated in the problem.

The problem said vaguely to index by date.
The delete 'state' I found out only by trial and error.
It also took me a long time to figure out.
"Important: The output should be a DataFrame, containing all of the columns of the dataset for the corresponding row."
all of the columns... so why do I have to delete ['state'] to pass? makes no sense.❓
Anyway, the code above and the one I posted in the comment in your code works.
So, it was not a very clearly stated problem.🤔

Bob_Li This seems to be an example of scope creep.
1.Dataframe output-specified
2.Ratio specified
3.Removal of ratio column NOT SPECIFIED.
4.Rearrangement - NOT INDICATED
In other words,
This is a poorly defined problem,and, should be indicated as such.

Bob_Li Sir, take a peek at this revised code...seems okay but results indicate otherwise...

Bob_Li It is not state but ratio. Still no correct answer.

i tried both codes and they passed. Did you try the one I wrote your code comment?
removal of state column, not ratio column., I tried it both ways...
now I'm confused...😲

🤔🤔🤔very strange..
The codes I gave you passes.
Try a direct copy paste.
Or maybe one of our. Sololearn app was not updated? Or there'a a difference in the app and web version? I'm on the app.
