solve this in python. tnx $|$Task $4.$ Definirajte aiohttp poslu$$itelj koji radi na portu $8081.$ Poslu$$itelj mora imati dvije rute: $/$proizvodi i $/$proizvodi$/\backslash \{$id$\backslash \}.$ Prva ruta vra$$a listu proizvoda u JSON formatu, a druga rutu vra$$a to$$no jedan proizvod prema ID$-$u$.$ Ako proizvod s tra$$enim ID$-$em ne postoji, vratite odgovor s statusom $404$ i porukom $\backslash \{\text{'}$error$\text{'}$: 'Proizvod s tra$$enim ID$-$em ne postoji'$\backslash \}.$

Proizvode pohranite u listu rje$$nika:

$```$

proizvodi $=[$

$\{"$id$"$: $1,$ "naziv": "Laptop", "cijena": $5000\},$

$\{"$id$"$: $2,$ "naziv": "Mis$",$ "cijena": $100\},$

$\{"$id$"$: $3,$ "naziv": "Tipkovnica", "cijena": $200\},$

$\{"$id$"$: $4,$ "naziv": "Monitor", "cijena": $1000\},$

$\{"$id$"$: $5,$ "naziv": "slus$$alice$",$ "cijena": $50\}$

J

$```$

within the main coroutine of the same script.

Test the server for all cases through a client session

Task $5.$ Upgrade the server from the previous task to also support the POST method on the $/$orders path.

This route receives JSON data about a new order in the following format. To begin, imagine that each order is simple and contains only one product and the quantity ordered:

$```$

$\{$

"proizvod$\_$id$"$: $1,$

"kolicina": $2$

$\}$

$```$

The handler coroutine of this method must check if the product with the requested ID exists within the products list $.$If it does not exist, return a response with status $404$ and message $\backslash \{\text{'}$error$\text{'}$: 'Product with requested ID does not

exist'$\backslash \}.$ If the product exists, add a new order to the orders list and return a response with the completed orders list in JSON format and the appropriate status code.

Define the orders list globally, as an empty list.

Your final server must contain $3$ routes: $/$products$,/$products$/\backslash \{$id$\backslash \}$ and $/$orders $.$

Test the server for all cases through a client session within the main coroutine of the same script.
