[Tutor] exercise correct ??

[Roelof Wobben]

Hello, 

 

Oke, the 4 is a starting point for the index.

 

Next problem.

 

The begin looks like this :

 

 index_of(5, (1, 2, 4, 5, 6, 10, 5, 5), 4)


But in the module I get this result :

 

val = 5

seq = (1, 2, 4, 5, 6, 10, 5, 5

 

So the 4 is not avaible anymore.

 

Now I can change the header to  index(val, seq, start=0) to index (val, seq, start)

But I think that's not what the exercise wants.

 

Is there another way I can use the 4 ?
