I'm trying to use **\w{2}\d/\d{1,2}(/\d{1,2})?** in order to match the following two interfaces on a Cisco switch:

Gi1/0/1 

Fa0/1

1. When I use re.search(), it returns the desired output.

```
import re
port = "Gi1/0/1 Fa0/1"
search = re.search(r'\w{2}\d/\d{1,2}(/\d{1,2})?', port)
print search.group()

```

I get **"Gi1/0/1"** as the output.

2. When I use re.findall()

```
import re
port = "Gi1/0/1 Fa0/1"
search = re.findall(r'\w{2}\d/\d{1,2}(/\d{1,2})?', port)
print search

```

I get **"['/1', '']"** which is undesired.

Why does't findall() return **['Gi1/0/1','Fa0/1']**?

Is that because I used **(/\d{1,2})?**, and findall() is supposed to return this part? Why is that? 

How do we get **['Gi1/0/1','Fa0/1']** using findall()?
