Python Dictionary Visualizer

See how dictionary keys are hashed, stored, updated, and retrieved step by step.

Visual learning • Step-by-step operations • Hash-based lookup concepts

This is a simplified conceptual model for learning. It helps explain hashing, buckets, and collisions without claiming to match every low-level CPython detail.

Current dictionary (Python view)

This is what Python code “sees”. Internal storage can look different.

{

}

Internal storage (concept)

We model a hash table as an array of buckets. Collisions are handled with chaining.

Bucket count
12
Bucket 0
empty
Empty slot.
Bucket 1
empty
Empty slot.
Bucket 2
empty
Empty slot.
Bucket 3
empty
Empty slot.
Bucket 4
empty
Empty slot.
Bucket 5
empty
Empty slot.
Bucket 6
empty
Empty slot.
Bucket 7
empty
Empty slot.
Bucket 8
empty
Empty slot.
Bucket 9
empty
Empty slot.
Bucket 10
empty
Empty slot.
Bucket 11
empty
Empty slot.

Step explanation

Each operation follows the same “hash → bucket → compare → act” idea.

Execute an operation to see step-by-step explanations and bucket highlights.
