Build a Hash Table - Build a Hash Table

Python

Tell us what’s happening:

If key is not in self.collection[key_hash], the method doesn’t raise an error or remove anything, it just returns. I can’t figure out from the console.log messages why I’m not passing test 10.

Your code so far

class HashTable():
    def __init__(self):
        self.collection = {}
    
    def hash(self, string):
        hash_sum = 0
        for char in string:
            hash_sum += ord(char)
        return hash_sum

    def add(self, key, value):
        key_hash = hash(key)
        if key_hash not in self.collection:
            self.collection[key_hash] = {}
        self.collection[key_hash][key] = value

    def remove(self, key):
        key_hash = hash(key)
        if key_hash in self.collection:
            if key in self.collection[key_hash]:
                del self.collection[key_hash][key]
        return

I resolved it – I wasn’t referencing self.hash(). With that updated, all tests pass.
