How do you disassemble Python functions into CPython bytecode instructions (LOAD_FAST, BINARY_OP) using the dis module?
❓ Interview Prompt: Explain `dis` module, CPython stack virtual machine, inspecting bytecode instructions (`LOAD_FAST`, `BINARY_OP`, `RETURN_VALUE`), and performance analysis.
The 'dis' module disassembles Python functions into human-readable CPython stack virtual machine bytecode instructions:
Why disassemble code?
•
Understand low-level execution performance differences between code alternatives.
•
Verify if global variable lookups ('LOAD_GLOBAL') can be optimized to local variable lookups ('LOAD_FAST').
Code Implementation Example
python
import dis
def add(a, b):
return a + b
# Disassemble function into CPython bytecode instructions
dis.dis(add)💡Disassembling Python function bytecode using dis.dis().
🎯 Interview Key Takeaway
Use the dis module to inspect CPython stack virtual machine bytecode instructions.
