Writing the if statement like this would produce the wrong result if $x==2$ or $3$ or $5$ or $7.$ What should your condition be instead?

In Code $2,$ why can we put the function call sign $($number$)$ inside the print statement? Consider the following change to the sign function. In the given code, the sign function returns data, but in the version below it prints it instead. What happens if you use the same main code and why?

def num$)$:

if num $>$ :

print$("$positive$")$

elif num $<mtext\; id="EditorElement\_22651"></mtext><mi\; id="EditorElement\_22614"></mi>$ :

print$("$negative$")$

else:

print$("$zero$")$

In Code $4,$ what happens if you remove money $=$ from the front of the last four lines of code? Why do you think this happens? Please post your output for $$5,$ for example.

In Code $5,$ none of the print statements in the function execute no matter how much money you input. Why do you think that happens?
