I need to get the index name from my DataFrame when I use a for loop.

My DataFrame looks like this:

```
+---------+------+
| Country | Code |
+---------+------+
| ABW     |  944 |
| AFG     |  761 |
| AGO     |  586 |
+---------+------+

```

I've tried this code:

```py
for index, nb_indicateurs in explore['2010'].iterrows():
    print(index)

```

But it gives this error:

> 
> 'Series' object has no attribute 'iterrows'
> 
> 
> 

Can someone help me??
