Setting up the Key-Value Store Class

For our simple key-value store, we'll start by creating a Python class called KeyValueStore. This class will serve as the foundation for our store and will initially only contain an empty dictionary to hold our keys and values.

1class KeyValueStore:
2    def __init__(self):
3        self.store = {}

In the above code, the KeyValueStore class has a constructor (__init__ method) that initializes an empty dictionary, store. This dictionary will play the role of our in-memory key-value store, much like Python's dict or a HashMap in Java.

Next, let's instantiate our KeyValueStore and confirm that it's been created properly:

1if __name__ == '__main__':
2    kvStore = KeyValueStore()
3    print('KeyValueStore instance created:', kvStore)

This code creates an instance of our KeyValueStore class and prints a confirmation message. At this point, the store attribute is an empty dictionary.

class KeyValueStore:

    def __init__(self):

        self.store = {}

​

if __name__ == '__main__':

    kvStore = KeyValueStore()

    print('KeyValueStore instance created:', kvStore)
