TypeError: 'Value' object does not support item assignment

Question

thank you for your help.

I am working with Orange3 (and loving it)... I am aggregating large amounts of data and processing it for normalization, formatting and logical analysis.

I am using python to manipulate data in fields.

Here is a code snip:

new_data = in_data.copy()
        for d in new_data:
        for f in d.domain.attributes:
            #print(f)
            if f.name == "Phone":
                counter+=1

                inan = np.isnan(d["Phone"])
                print("NaN Check: " + str(inan))

                fph = str(phone_format(d["Phone"].value))

                print(str(counter) + ": " + fph)
                d[f]["Phone"]=str(fph)

TypeError: 'Value' object does not support item assignment

This is the offending line of code: d[f]["Phone"]=str(fph)

Will someone kindly advise me of the correct? and pythonic (if possible) way to update the specific field during an iterative investigation?

Thanks in advance!

If you want to modify values for Orange.data.Table, you will have to set the correct value in your new_data.X, which is 2D numpy table of floats. It can not contain strings. Strings in Orange.data.Table can only be stored as meta attributes. – Marko Toplak 8 hours ago <

@MarkoToplak you were spot on... I had to modify the inputs to be meta/text and reload the file which made assignment possible. THANK YOU! – objectAntics just now Edit Delete

new_data[counter]["Phone"] = fph
