version: "1.0.1" name: idapython description: IDA Pro Python scripting for reverse engineering. Use when writing IDAPython scripts, analyzing binaries, working with IDA's API for disassembly, decompilation (Hex-Rays), type systems, cross-references, functions, segments, or any IDA database manipulation. Covers ida_* modules (50+), idautils iterators, and common patterns.

IDAPython

Use modern ida_* modules. Avoid legacy idc module.

Core Patterns

Iterate functions

python

for ea in idautils.Functions():
    name = ida_funcs.get_func_name(ea)
    func = ida_funcs.get_func(ea)

Iterate instructions in function

python

for head in idautils.FuncItems(func_ea):
    insn = ida_ua.insn_t()
    if ida_ua.decode_insn(insn, head):
        print(f"{head:#x}: {insn.itype}")

Cross-references

python

for xref in idautils.XrefsTo(ea):
    print(f"{xref.frm:#x} -> {xref.to:#x} type={xref.type}")

Read/write bytes

python

data = ida_bytes.get_bytes(ea, size)
ida_bytes.patch_bytes(ea, b"\x90\x90")

Names

python

name = ida_name.get_name(ea)
ida_name.set_name(ea, "new_name", ida_name.SN_NOCHECK)

Decompile function

python

cfunc = ida_hexrays.decompile(ea)
if cfunc:
    print(cfunc)  # pseudocode
    for lvar in cfunc.lvars:
        print(f"{lvar.name}: {lvar.type()}")

Walk ctree (decompiled AST)

python

class MyVisitor(ida_hexrays.ctree_visitor_t):
    def visit_expr(self, e):
        if e.op == ida_hexrays.cot_call:
            print(f"Call at {e.ea:#x}")
        return 0
cfunc = ida_hexrays.decompile(ea)
MyVisitor().apply_to(cfunc.body, None)

Apply type

python

tif = ida_typeinf.tinfo_t()
if ida_typeinf.parse_decl(tif, None, "int (*)(char *, int)", 0):
    ida_typeinf.apply_tinfo(ea, tif, ida_typeinf.TINFO_DEFINITE)

Create structure

python

udt = ida_typeinf.udt_type_data_t()
m = ida_typeinf.udm_t()
m.name = "field1"
m.type = ida_typeinf.tinfo_t(ida_typeinf.BTF_INT32)
m.offset = 0
m.size = 4
udt.push_back(m)
tif = ida_typeinf.tinfo_t()
tif.create_udt(udt, ida_typeinf.BTF_STRUCT)
tif.set_named_type(ida_typeinf.get_idati(), "MyStruct")

Strings list

python

for s in idautils.Strings():
    print(f"{s.ea:#x}: {str(s)}")

Wait for analysis

python

ida_auto.auto_wait()  # Block until autoanalysis completes

Key Constants

Constant	Value/Use
`BADADDR`	Invalid address sentinel
`ida_name.SN_NOCHECK`	Skip name validation
`ida_typeinf.TINFO_DEFINITE`	Force type application
`o_reg`, `o_mem`, `o_imm`, `o_displ`, `o_near`	Operand types
`dt_byte`, `dt_word`, `dt_dword`, `dt_qword`	Data types
`fl_CF`, `fl_CN`, `fl_JF`, `fl_JN`, `fl_F`	Code xref types
`dr_R`, `dr_W`, `dr_O`	Data xref types

Critical Rules

NEVER convert hex/decimal manually — use int_convert MCP tool
Wait for analysis: Call ida_auto.auto_wait() before reading results
Thread safety: IDA SDK calls must run on main thread (use @idasync)
64-bit addresses: Always assume ea_t can be 64-bit

Anti-Patterns

Avoid	Do Instead
`idc.*` functions	Use `ida_*` modules
Hardcoded addresses	Use names, patterns, or xrefs
Manual hex conversion	Use `int_convert` tool
Blocking main thread	Use `execute_sync()` for long ops
Guessing at types	Derive from disassembly/decompilation
