How to parse field names of a C struct in python?

I have a C struct in cfile.c as a global variable, and i want to be able to access and change it from a python file.

The c struct in the .h file:

typedef struct _attribute((packed_)) MyStruct
{
    SomeOtherStruct x1[MAX_LEN];
    uint8_t x2;
                             
} MyStruct; 

the definition of the struct in the .c file (value insertion is in some other place in the code):

MyStruct my_cfg;

What i did was compiling the file and creating a dll file, and then wrote to next python lines:

class my_struct(ctypes.Structure):
    fields = (
        ("x1",ctypes.struct),
        ("x2",ctypes.c_uint32))
    def _repr_(self) -> str:
        return super()._repr_()


def main():

    host_dll = ctypes.CDLL('path-to-dll')
    strct = my_struct.in_dll(host_dll,'my_cfg')

After these lines i was able to access the struct fields using the variable 'strct' as i wanted. But, i don't want to define the fields 2 times like i do now - one time in the .h file and a second time in the .py file in the 'my_struct' class.

How can i get the names of the struct's fields? Is there a way to do it using the ctypes library? Or do i have to access the .h from the python script and parse it myself? if so, is there a parser for c struct in python?

I didn't find something like this in my online search.

Also, I would like to hear other ways to access and change a C struct from a python file is someone knows a better way.
