Error in location_data.unique()
When I reproduce the above code in jupyter, I get the error message below. Thanks very much.
Addendum: Actually, I got error messages every time I used 'unique', as shown below:
Thanks for reaching out.
DataFrame object has no attribute 'unique' occurs because the
unique() function is not a direct attribute of a
DataFrame object in
To get the unique values from a column or Series within a DataFrame, you can use the unique() function on that specific column or Series.
location_data is a Series object instead of a DataFrame, the
unique() function would work without producing the error.
Thus, I assume that earlier in your code you created a DataFrame with the same name. Please try to restart Kernel and re-execute the code cells after creating a Series object in a new document.
Hope this helps.
Thanks for your quick reply. I re-started the kernel, but obtained the same mistake. I did not create a dataFrame before with the same name, I have been copying everything from the video class into jupyter.
I also tried the same code in a different document but obtained the same error messages.
However, as regards it being a Series object or a dataFrame, I did obtain the results below that I don't know how to interpret:
Thanks again. Best, Vânia
The reason you have a DataFrame instead of a Series, as shown in the lesson, is because you didn't utilize the
squeeze parameter when creating the variable that holds the data from the resources.
squeeze=True is used, the output is returned as a Series object instead of a DataFrame.
data = pd.read_csv('Location.csv', squeeze = True)
After fixing that, your code should work as intended.
Hope this helps.
