> I apologise for repeatedly asking, but I still need a more specific clarification regarding this case. The line 'Whitespace can only appear at the beginning of a line if it is a tab under a function definition' is said to be true but whitespace and tab are not the same, so it is a bit confusing to me. Assuming that line only means the tab character '\t', I am under the impression that any line beginning with whitespace would cause an error, please let me know if I am misunderstanding.
