can you help me with modify section function:modify$\_$section

$($str$,$ str$,$ int, int$)->$ str

The first parameter represents the game state, the second parameter is the move to be applied to the string, the third parameter is the section number of the section to be modified, and the fourth parameter is the section length.

You may assume the move will be one of ROTATE or SWAP $($the str value representing each can be seen in the constants provided for you at the top of the starter code$)$ and that the third parameter is a valid section number.

This function will return a new string that reflects the updated game state after applying the given move to the specified section. For example, the function call modify$\_$section$(\text{'}$teerkocrlkae$\text{'}$def modify$\_$section$($game$\_$state: str$,$ move: str$,$ section$\_$num: int, section$\_$length

: int$)->$ str:

$"""$ Given a scrambled string, move, section number, and section length,

return a new string that reflects the updated game state after applying

the move to the specified section

$>>>$ modify$\_$section$(\text{'}$teerkocrlake$\text{'},$ 'SWAP', $2,4)$

'teerrocklkae'

$>>>$ modify$\_$section$(\text{'}$btuterfly$\text{'},$ 'SWAP',$2,2)$

'butterfly'

$>>>$ modify$\_$section$(\text{'}$ockrhill$\text{'},\text{'}$R$\text{'},2,4)$

'rockhill'

$"""$

start $=$ get$\_$section$\_$start$($section$\_$num, section$\_$length$)$

end $=$ start $+$ section$\_$length

if move $==$ SWAP:

new$\_$game$\_$state $=$ game$\_$state$[$:start$]+$ game$\_$state$[$end$-1]$

$+$ game$\_$state$[$start$+1$:end$-1]+$ game$\_$state$[$start:$]+$ game$\_$state$[$end:$]$

elif move $==$ ROTATE:

new$\_$game$\_$state $=$ game$\_$state$[$:start$]+$ game$\_$state$[$end$-1$ : start:$-1]$

$+$ game$\_$state$[$start$]+$ game$\_$state$[$end:$]$

else :

new$\_$game$\_$state $=$ game$\_$state

return new$\_$game$\_$state

however neither swap or rotate seems to work pls help as asap with right code
