opcode Module¶
The opcode module provides access to Python's bytecode opcodes and their properties, useful for bytecode analysis and manipulation.
Complexity Reference¶
| Operation | Time | Space | Notes |
|---|---|---|---|
| Access opcode | O(1) | O(1) | Hash lookup |
| Get opcode info | O(1) | O(1) | Static data |
Bytecode Opcode Information¶
Accessing Opcodes¶
import opcode
# Get opcode number - O(1)
print(opcode.opmap['LOAD_CONST'])
print(opcode.opmap['RETURN_VALUE'])
# Get opcode name - O(1)
print(opcode.opname[opcode.opmap['LOAD_CONST']])
# Check if opcode has argument threshold - O(1)
print(opcode.HAVE_ARGUMENT)
# Compare opcodes - O(1)
if opcode.opmap['STORE_NAME'] > opcode.HAVE_ARGUMENT:
print("Has argument")
