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]

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

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.

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.

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)
