Question

The logical error in the following program is that ____________________

for n in range(5):

number = int(input('Enter a whole number: '))

total += number

print ('The total is: ', total)

		variable total should be a string
		variable number should be float
		variable total is not initialized, should be assigned 0 before the loop
		there should be end='' after 'Enter a whole number' What will the following code do?               SIZE = 5          x = [2.1]*SIZE it multiplies the value 2.1 by 5 to give 10.5 it creates five separate lists named x1, x2, x3, x4, and x5 it assigns 2.1 to each position in the list, except the last it expands list x to now have 5 positions, each position in the list is assigned 2.1 The purpose of a repetition structure (also called a loop) in a program is _________________. to reduce the time it takes the program to run to enable inputs to be stored in distinct separate variables to select some code in the program to be executed exactly once to code a group of statements only once that will be run multiple times when the program executes The part or the region of the program where a variable may be used is called the _____________ of the variable. lifetime span scope interval

Answer 1

Answer:

1)  variable total is not initialized, should be assigned 0 before the loop
2)  it expands list x to now have 5 positions, each position in the list is assigned 2.1
3)  to code a group of statements only once that will be run multiple times when the program executes
4)  scope
