Question: I'm trying to drop the last row in a `dataframe` created by pandas in python and seem to be having trouble. 

```
index = DateRange('1/1/2000', periods=8)
df = DataFrame(randn(8, 3), index=index, columns=['A', 'B', 'C'])

```

I tried the drop method like this:

```
df.drop([shape(df)[0]-1], axis = 0)

```

but it keeps saying label not contained in the axis. 

I also tried to drop by index name and it still doesn't seem to be working.

Any advice would be appreciated. Thanks!!!

Answer: 
I'm use the following code and resolve problem.

```
$('.colorBox').colorbox({
     scalePhotos: true,
     maxWidth: '100%'
});

```
That result makes sense to me. You gave colorbox a display:block element with no defined width and asked it to estimate the size, which of course will be 100% of the available width.
