## TODO

- [x] Change all `sympy` to `diofant`

cffi is better than ctypes.

### cffi

```py

from cffi import FFI

ffi = FFI()

ffi.cdef("double key(int n);")

lib = ffi.dlopen("./69.dll")

```

### ctypes

```py

from ctypes import CDLL, CFUNCTYPE, c_double, c_int

key = CDLL("./69.dll").key

key = CFUNCTYPE(c_double, c_int)(key)

```

## Some other information

This is very useful [pytcc](https://github.com/thgcode/pytcc)

Thanks to [CodeHz](https://github.com/codehz/) for advice.

tcc 不需要生成 dll 啊

CodeHz 📡, [22.02.21 20:03]

可以直接 relocate

CodeHz 📡, [22.02.21 20:03]

速度更快

看头文件

还有 tcc_get_symbol

CodeHz 📡, [22.02.21 20:12]

重定位后直接拿符号

CodeHz 📡, [22.02.21 20:12]

很香

CodeHz 📡, [22.02.21 20:13]

可以拿来做 naive jit
