Let's say I have two objects of a same class: objA and objB. Their relationship is the following:

(objA == objB)    #true
(objA is objB)    #false

If I use both objects as keys in a Python dict, then they will be considered as the same key, and overwrite each other. Is there a way to override the dict comparator to use the is comparison instead of == so that the two objects will be seen as different keys in the dict?

Maybe I can override the equals method in the class or something? To be more specific, I am talking about two Tag objects from the BeautifulSoup4 library.

Here's a more specific example of what I am talking about:

from bs4 import BeautifulSoup

HTML_string = "
some_header
some_header
"

HTML_soup = BeautifulSoup(HTML_string, 'lxml')

first_h1 = HTML_soup.find_all('h1')[0]      #first_h1 = 
some_header
second_h1 = HTML_soup.find_all('h1')[1]     #second_h1 = 
some_header

print(first_h1 == second_h1)        # this prints True
print(first_h1 is second_h1)        # this prints False

my_dict = {}
my_dict[first_h1] = 1
my_dict[second_h1] = 1

print(len(my_dict))                 # my dict has only 1 entry!

# I want to have 2 entries in my_dict: one for key 'first_h1', one for key 'second_h1'.
