String indices must be integer - they are

I have some code that generates some a start and end position using string.find.

I then substring the string using the string positions.

The code fails with indices must be integers.

Just to make sure they are integers, I have cast them.

Here's the code snippet with a print to show the values: 

 print("s={0}  e={1}".format(s, e))
 grab=source[int(s), int(e)]

and here's the output:

s=7478  e=7690
Exception "unhandled TypeError"
string indices must be integers

I'm obviously missing something but I have no idea what.

Any ideas anyone?

You've used a Tuple[int, int] as the index instead of an int. You probably meant to use the slice notation, which uses a : instead of a ,:

source[int(s):int(e)]
