Answer 1

x=y=3
while x+y>2:
print (x)
x=x-1

look, here x = 3
not 6
but x + y = 6 (before going to loop)

On the time of first iteraion you print x (3) and reduce x's value to 2

then x + y = 5
and that's how the iteration goes on and prints

3
2
1
0

Answer 2

# while loop

x=y=3
z=x+y
while z>2:
print (z)
z=z-1

Answer 3

You were just printing the variable x, you never saved the value of the sum of x and y in a variable

Answer 4

I think inorder for it to output 654321 the code should be
x=y=6
While x+y>6
Print(x)
X=x-1

Answer 5

Don't know about the quiz but,
1st iteration: Your while loop began with the condition 6>3 ; which is true
The loop runs and x is printed and then reduced to 2 from 3.

2nd iteration: now check for 2+3>3, which is true.
Loop runs again and prints x (which is 2 now) and then reduces x from 2 to 1.

3rd iteration: x is 1 and y is still 3, so x+y>3, True again.
Loop runs and x, which is now 1, is printed then gets reduced to 0.

4th iteration: x is 0 and y is 3, x+y > 3 is FALSE now. (3>3 is Wrong).
LOOP DOESN'T RUN ANYMORE!
once the condition is false, loop is bypassed! Its work is done and you can forget about it now.

Answer 6

you print only the value of x..3 instead of x+y

Answer 7

Replace line number 7 with "print (x+y) " and here you go. :-)

Answer 8

That was a good one ClassHacker :p

Answer 9

You were printing the value of x not the sum.

Answer 10

x=y=3
while (x+y)>2:
print (x+y)
x=x-1

Answer 11

I still dont understnd how does it become a 5? and I can see that it is 3 then -1 it can go to zero?

Answer 12

x by its self is 3, I can understand that

Answer 13

wow , thanks all of you, that was mind boggling
