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**.
Instead of using

```
df = pd.dataframe()
df['Neighbourhoods'] = Neighbourhoods

```

You can use 

```
df['Neighbourhoods'] = pd.Series(Neighbourhoods)

```

This would solve your error and add new columns similarly using pd.Series(listname) or you can give list of lists containing PostalCode, Borough, and Neighborhoods using this code

```
df = pd.Dataframe(list_of_lists)

```
