help() performance and internals

Performance characteristics and CPython implementation details.

python
# help() internals
import dis

def using_help():
    pass

# Bytecode analysis
dis.dis(using_help)

# Check if it's truly built-in
import builtins
print(f"\nhelp is builtin: {hasattr(builtins, 'help')}")
print(f"Type: {type(builtins.help)}")

Understanding the internal implementation helps optimize hot paths in performance-critical code.
