input() performance and internals

Performance characteristics and CPython implementation details.

python
# input() internals
import dis

def using_input():
    pass

# Bytecode analysis
dis.dis(using_input)

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

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