Question: I have two times and I want to subtract them by using a PHP built-in function or Carbon. For example, I have following times:

1. `00:05:10`, i.e. 5 Minutes 10 Seconds
2. `00:03:10`, i.e. 3 Minutes 10 Seconds

If I subtract them, the total time would be 00:08:20. Can someone kindly guide me how I can make such a subtraction?

Answer: 
pandas allow you to do it in one line of code:

`df = pd.read_html('https://en.wikipedia.org/wiki/List_of_postal_codes_of_Canada:_M')[0]`

You have two small errors:

`df = pd.dataframe()` should be `df = pd.DataFrame([])`

You also misspelled `Neighborhoods` as `Neighbourhoods` the second time.

You might also need to change `soup = BeautifulSoup(website_url,'lxml')` to `soup = BeautifulSoup(website_url,'xml')`, but we can't help you more without knowing your exact error message.
