while loop help

[jhall710]

Hey everyone, have all of my code correct thus far (so I think lol) but steps 6 & 7 have me very lost. My instructor never gave us any information on swaps and I'm thinking there is to be a loop within a loop but i'm not sure if that is even possible with python. Appreciate any help/direction

1. Draw five adjacent boxes and number the boxes 0 though 4
   
   
2. Put the following numbers in boxes 0 - 4, one number per box: 6 8 4 5 2
   

1. Draw a box, label the box I, write the number 0 in box I
   
   
2. Draw a box, label the box J, write the number 999 in box J
   
   
3. If the number in box I is less than 5 then do the next instruction, otherwise do instruction 12
   
   
4. Replace the number in box J with 0
   
   
5. If the number in box J is less than 4 then do the next instruction, otherwise do instruction 10
   
   
6. If the number in the numbered box whose box number is the same as the number in box J is greater than the number in the box that follows then do the next instruction, otherwise do instruction 8
   
   
7. Swap the value in the box whose box number is the same as the number in box J with the value in the box that follows
   
   
8. Replace the number in box J with the number that is one more than the number currently in box J
   
   
9. Go back and do instruction 5 again
   
   
10. Replace the number in box I with the number that is one more than the number currently in box I
    
    
11. Go back and do instruction 3 again
    
    
12. You are done
    

list_ = [6,8,4,5,2]
I = 0
J = 999
while I < 5:
  J = 0
  while J < 4:
    
    
  J = J + 1
  I = I + 1
