slice() — Expert Examples
Creates a slice object for use in extended indexing
slice() performance and internals
Performance characteristics and CPython implementation details.
python
# slice() internals import dis def using_slice(): pass # Bytecode analysis dis.dis(using_slice) # Check if it's truly built-in import builtins print(f"\nslice is builtin: {hasattr(builtins, 'slice')}") print(f"Type: {type(builtins.slice)}")
Understanding the internal implementation helps optimize hot paths in performance-critical code.
