Canonical Hash
Deterministic hashing for arbitrary Python objects.
Provides utilities for creating stable, deterministic hashes of Python objects, essential for cache key computation, data versioning, and reproducibility.
Usage
from scicanonicalhash import canonical_hash, generate_record_id
# Hash any supported Python object
h = canonical_hash(42)
h = canonical_hash([1, 2, 3])
h = canonical_hash({"key": "value"})
# Generates a 16-character hex string (first 64 bits of SHA-256)
assert len(h) == 16
assert canonical_hash(42) == canonical_hash(42) # Deterministic
Supported Types
- JSON-serializable primitives (None, bool, int, float, str)
- numpy ndarrays (via shape + dtype + raw bytes)
- pandas DataFrames (via columns + index + array serialization)
- pandas Series (via name + array serialization)
- Dicts (sorted keys, recursive serialization)
- Lists/tuples (order-preserving, recursive serialization)
- Datetimes:
datetime.datetime,pd.Timestamp,np.datetime64(any unit) and NaT. One spelling across the three types for the same value; an aware value hashes its UTC instant PLUS its zone label (zone_label: IANA name,"UTC", or a fixed offset like"+02:00"), which sciduckdb stores and restores. Owner:scicanonicalhash.datetimes.datetime64ARRAYS keep their raw-bytes form.
generate_record_id
Generate a unique record ID from type, schema version, content hash, and metadata:
rid = generate_record_id("MyData", 1, "abc123", {"subject": 1})
