I just written this code for this question, please see the message at the bottom after I have ran the code and please advise what could be wrong then fix it for me$.$

We've loaded a dataset below relating to fraud on an E$-$commerce website. The fields in the dataset are

'user$\_$id$\text{'},$'browser', 'age', 'purchase$\_$value', "fraud'.

Find the count of different types of browsers used in this dataset. Save the result as browser$\_$counts and

print it$.$

Using the list of unique browser types obtained in the previous step, convert browser to a categorical

variable type $(\text{'}$category$\text{'}).$

Using cat.codes, calculate the value that corresponds to the median value of browser, save it as a

variable named median$\_$browser$\_$used and print the result.

Did you use $.$value$\_$counts$()$ to get counts of browsers used by type?
