Create a dictionary using curly braces {} or the dict() function to represent the hashmap.

Add key-value pairs by assigning values to keys using the syntax dictionary[key] = value.

Retrieve values by specifying the key in square brackets, e.g., dictionary[key], or use the .get() method to avoid errors for non-existent keys.

Update values by reassigning a new value to an existing key using the same syntax as adding a key-value pair.

Delete key-value pairs using the del keyword, e.g., del dictionary[key], or the .pop() method to remove a key and retrieve its value.

Loop through the dictionary using .items() to access both keys and values, .keys() for keys, or .values() for values.

Use the in keyword to check if a key exists in the dictionary.

Clear all key-value pairs using the .clear() method if needed.

For advanced use cases, consider using defaultdict from the collections module to handle missing keys with default values.
