type() — Expert Examples
Returns the type of an object, or creates a new type dynamically
type() performance and internals
Performance characteristics and CPython implementation details.
python
# type() internals import dis def using_type(): return type(42) # Bytecode analysis dis.dis(using_type) # Check if it's truly built-in import builtins print(f"\ntype is builtin: {hasattr(builtins, 'type')}") print(f"Type: {type(builtins.type)}")
Understanding the internal implementation helps optimize hot paths in performance-critical code.
