Answer 1

Answer #1

Yes given Code is Wrong and these two options are the reason behind that :

Option 3) The function swap() should return the swapped values, so main() can access it.

Option 4) The function swap() does not currently swap the values a and b. This is a logical error

This code has a logical error

If we use
a = b, original value of a will be lost and during
temp = a, temp will also have the new value of 'a' i.e. a=b So you can't return multiple values in functions.

To make it happen, you have to create global variables that are accessible to both functions.

So Correct Code for this program will be

def main():
x=10
y=2
x, y=swap(x,y)
print(x,y)

def swap(a, b):
temp=a
a=b
b=temp
return (a,b)
main()

This program should use a main function and two other functions named playlist and savelist as follows: The main function: The main function should create an empty list named nums and then use a loop to add ten integers to nums, each integer in the range from 10-90. NOTE: In Python, a list is a data type. See Chapter 7. The main function should then call the playlist function and savelist function, in that order. Both of these functions take...
