Returns the type of an object, or creates a new type dynamically

Python Playground

# 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)}")
