Basically, if I have a line of text which starts with indention, what's the best way to grab that indention and put it into a variable in Python? For example, if the line is:

```
\t\tthis line has two tabs of indention

```

Then it would return '\t\t'. Or, if the line was:

```
    this line has four spaces of indention

```

Then it would return four spaces.

So I guess you could say that I just need to strip everything from a string from first non-whitespace character to the end. Thoughts?
