And for your original code:

* You're comparing line.isspace, not line.isspace()
* line.isspace() is only true if the entire line is spaces.
* You're updating start, but your inner while doesn't change the comparison.

I suspect you intended the inner while to instead be if line[start].isspace() == False:

But the split() version is better.

You are absolutely right, i forgot the [start]-part and now it is working. However now i get a "string index out of range error", any idea why?
