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: 
Provide the error message. 
By looking at it, first you have df['Neighbourhoods'] = **Neighbourhoods** where your list has the name **Neighborhoods**.
It looks like you're only picking up one of the columns here:

```
links = My_table.findAll('a')

```

You should be looking for `'tr'` rather than `'a'` as that signifies a new row in the table.

You should then use a for loop to populate a list of lists, this code should work:

```
v = []
 for tr in values:
   td = tr.find_all('td')
   row = [i.text for i in td]
   v.append(row)
 df = pd.DataFrame.from_records(v)

```
