Common errors

error ImportError: cannot import name 'frozendict' from 'frozendict' (unknown location) ↓

cause The frozendict package is not installed; types-frozendict only provides type stubs.

fix

Install frozendict: pip install frozendict

error ModuleNotFoundError: No module named 'frozendict' ↓

cause Neither frozendict nor types-frozendict are installed.

fix

Install frozendict: pip install frozendict; optionally install types-frozendict for type hints.

error Cannot find implementation or library stub for module 'frozendict' ↓

cause Missing types-frozendict type stubs; the module exists but mypy can't find stubs.

fix

Install types-frozendict: pip install types-frozendict

Warnings

deprecated types-frozendict is part of typeshed and may be deprecated in favor of inline types if the frozendict project adds its own types. ↓

fix Monitor frozendict releases; if inline types are added, remove types-frozendict dependency and use frozendict directly.

gotcha The stubs only cover frozendict's public API. Custom subclasses or advanced features may not be typed. ↓

fix Add custom type stubs if using advanced features not covered by types-frozendict.

gotcha frozendict is hashable only if all its values are hashable. The stubs do not enforce this at type-check time. ↓

fix Use mypy or pyright with custom checks if needed, or ensure values are hashable at runtime.

Quickstart

Basic usage of frozendict and type hints provided by types-frozendict.

from frozendict import frozendict

# Create a frozen dict
fd = frozendict({"key": "value"})
print(fd["key"])  # Output: value

# Type hint example
def process(d: frozendict[str, int]) -> None:
    for k, v in d.items():
        print(k, v)

process(frozendict({"a": 1, "b": 2}))
