Which of the following statements is incorrect? There might be more than one incorrect statement, and you have to select all incorrect statements to receive full credit.

Together, blank lines, space characters, and tab characters are known as white space. Python ignores all white space.

A line that begins with the hash character (#) is a comment.

A comment must begin the line with a hash character (#).

You can construct any Python program from only six different forms of control (sequential execution, and the if, ifelse, ifelifelse, while, and for statements). You combine these in only two ways (control-statement stacking and control-statement nesting). This is the essence of simplicity.

A condition which evaluates to a nonzero value is considered to be True.

Strings containing characters are True and empty strings ('', "" or """""") are False.

Bohm and Jacopini demonstrated that all programs could be written using three forms of controlnamely, sequential execution, the selection statement, and the iteration statement.
