I am getting the following errors:

-Argument of type "int | None" cannot be assigned to parameter "__s" of type "slice" in function "__setitem__" Type "int | None" cannot be assigned to type "slice" "int" is incompatible with "slice"

-Argument of type "int | None" cannot be assigned to parameter "__s" of type "slice" in function "__setitem__" Type "int | None" cannot be assigned to type "slice" "int" is incompatible with "slice"

Here is the code:

#hash map

def gethash(key):

h=0

for x in key:

h+= ord(x)

return h%100

class hashtable:

def __init__(self):

self.MAX = 100

self.arr = [None for i in range(self.MAX)]

def get_hash(self,key):

h =0

for char in key:

h+= ord(char)

return h % self.MAX

def __setitem__(self,key,val):

h = self.get_hash(key)

self.arr[h]= val

def __getitem__(self,key):

h =self.get_hash(key)

return self.arr[h]

what is wrong ?
