How would I write this C code in Python?

[DeveloperX]

I am trying to figure out how to rewrite the following chunk of code
in Python:

C source
[code]
typedef struct PF
{
  int flags;
  long user;
  char*filename;
  unsigned char buffer[MAXBUFFERSIZE];
} PF;

typedef BLOCK
{
  PF * packdata;
} BLOCK;

BLOCK* blocks;
[/code]

My first idea was to create a class for PF and a class for BLOCK, but
I got lost somewhere along the lines. :\

Python Attempt: Please note that since I can't type TABs online
easily, I am using the @ character to represent TABs in the following
Python code.
[code]
class PF:
@def __init__(self):
@@self.flags, self.user = 0, 0
@@self.filename = ''
@@self.buffer = []

class BLOCK:
@def __init__(self):
@@self.packdata = []

blocks = []
[/code]

Any Python Gurus out there that can help me?
