In the function keyword list. b. In the module docstring. c. In the function’s return list. d. In the function header. 3 points Question 4The main function usually expects no arguments and returns no value. True False 3.5 points Question 5What is the return value for a function that has no return statement defined? a. The function will return a NULL value. b. The function will return a value of True, provided there are no errors. c. The function will return a special value of None. d. The function will return a value of False. 3.5 points Question 6Functions that do not return a value are called ____ functions. a. null b. zero c. empty d. void 3.5 points Question 7If a function has no parameters, it does not need to have ( ) at the end of the function header. True False 3.5 points Question 8Once you write and properly debug a function, you can use it in the program again and again without having to rewrite the same code repeatedly. True False 3.5 points Question 9The execution of a return statement in a user-defined function ends the whole program. True False 3.5 points Question 10What is the final value of x?import mathx = math.ceil(5.2) 3.5 points Question 11What is the final value of v?import mathv = math.floor(26.9995) 3.5 points Question 12Using functions greatly enhances a program’s readability because it reduces the complexity of the function main.
