list() — Expert Examples
Creates a new list or converts an iterable into a list
list() performance and internals
Performance characteristics and CPython implementation details.
python
# list() internals import dis def using_list(): pass # Bytecode analysis dis.dis(using_list) # Check if it's truly built-in import builtins print(f"\nlist is builtin: {hasattr(builtins, 'list')}") print(f"Type: {type(builtins.list)}")
Understanding the internal implementation helps optimize hot paths in performance-critical code.
