following on with this question: 1. In the cases where 1 whitespace minimum is required (such as after function, return, print, between the function identifier and its parameters), can more whitespace be added without causing any error? 2. Can whitespace be inserted in a function call such as multiply(10, 5)? (e.g. multiply ( 10 , 5 ) 3. In a function body that must be indented with a tab character, is just one '\t' used in this case? Can the '\t' character be preceded or followed by any whitespace characters? Thank you!
