Write an implementation that satisfies the doc$-$string in the line which says "TODO your implementation here" using ONLY Pycharm, please.

Then, test the function using the lines of code which starts from right below "TODO your implementation here"

Thank you.

class Registry$($object$)$:

def $\_\_$init$\_\_($self$,$ size, value$)$:

$"""$

Purpose:

Initialize a registry of a give size filled with the

given value

Pre$-$conditions:

size: number of elements in the registry

value: the default initial value for all elements

$"""$

self.$\_\_$reg $=[$value for i in range$($size$)]$

def set$($self$,$ i$)$:

$"""$

Purpose:

Set the registry element at i to True

Pre$-$conditions:

i: an index, in the correct range for reg

Post$-$conditions:

the registry value at i is set to True

Return:

$($none$)$

$"""$

self.$\_\_$reg$[$i$]=$ True

def reset$($self$,$ i$)$:

$"""$

Purpose:

Set the registry element at i to False

Pre$-$conditions:

i: an index, in the correct range for reg

Post$-$conditions:

the registry value at i is set to False

Return:

$($none$)$

$"""$

self.$\_\_$reg$[$i$]=$ False

def is$\_$registered$($self$,$ i$)$:

$"""$

Purpose:

Returns the value stored at registry element i

Pre$-$conditions:

i: an index, in the correct range for reg

Post$-$conditions:

$($none$)$

Return:

the value stored at element i

$"""$

return self.$\_\_$reg$[$i$]$

def show$($self$)$:

$"""$

Purpose:

Shows the current Registry values

Pre$-$conditions:

$($none$)$

Post$-$conditions:

$($none$)$

Returns:

$($none$)$

$"""$

print$($self$.\_\_$reg$)$

def extend$($self$,$ size, value$)$:

$"""$

Purpose:

Extend the registry. This grows the registry to the given size.

The value given will be the new default value for the extended registers.

Pre$-$conditions:

size: number of elements in the registry

value: the default initial value for all elements

Post$-$conditions:

IMPORTANT: The previous entries in the registry retain their values.

The registry is expanded. Entries up to the original size are kept the same.

New entries are set to the value provided in the argument.

Returns:

$($none$)$

Warnings:

This method asserts that the new size is greater than the original Registry size.
