def __setitem__(self, key, value):
if key in self.keys_:
i = self.keys_.index(key)
self.values_[i] = value
else:
self.keys_.append(key)
self.values_.append(value)

def __getitem__(self, key):
i = self.keys_.index(key)
return self.values_[i]

Answer 2

Do you accept "5" as key?
In this case a blind converting to str will do it.

Answer 3

In this case
a) u can't work with set/get attribute or
b) u reserve a namespace for numerical attributes eg #5 #6 and convert to string.

Answer 4

setattr(self, key, value)

Why do you even need this, if you already have two lists to store keys and values?

According to documentation, the second argument of setattr must be a string.
https://docs.python.org/3/library/functions.html#setattr

Answer 5

If you want to be even more precise and similar to the API of the normal dict, you can even put this in the getter methods:

if key not in self.keys_:
raise KeyError

Instead of recreating a dict, you can inherit from UserDict.

import json
from urllib.request import urlopen
url = "https://raw.githubusercontent.com/matthewreagan/WebstersEnglishDictionary/master/dictionary.json"
response = urlopen(url)
data_json= json.loads(response.read())
word = input("Enter word to see the meaning!\n").lower().strip()
meaning = data_json.get(word)
if meaning is None:
print (f"Your search \"{word}\" not found in the dictionary!")
else:
'''
for i in meaning:
if i.isdigit():
meaning = meaning .replace(i,i+"\n"
'''
print(meaning)
