I have 2 lists as below:

```
bob = ['Bob Smith', 42, 30000, 'software']
sue = ['Sue Jones', 45, 40000, 'hardware']

```

the statement 

```
print bob[0].split()[-1]

```

gives me Smith

I wanted to get more information regarding list therefore I used 2 commands:

```
help(list)
dir(list)

```

But neither showed that split is a method or object that can be used by lists. But as you can see above I can use split() with list element.

Can someone help me in this naive question. Am I looking at wrong places?

Regards
