Will fail if string is empty

"If the string is empty or doesn't have any letter in it - function should return True." <pre class='brush: python'>>>> is_all_upper("") True >>> is_all_upper(" ") True </pre> What's the problem?

I am having a hard time understand why this code return True for empty string. When I try bool(text.upper('')) return a False value.

bool(text.upper('')) First, that should not be generating "False". It SHOULD be generating "TypeError: upper() takes no arguments (1 given)". Second, EVEN IF that were syntactically correct (it's not), the quotation marks ('') would be evaluated, not an empty string. x = '' # create an empty string to evaluate first bool(x.upper()) # then check on the string assignment True

If text is the empty string, then text.upper() is ''.upper() (which is ''). Then <blockquote> text.upper() == text </blockquote> is <blockquote> ''.upper() == '' </blockquote> and this is True. (You should try bool(''.upper() == ''))
