[Tutor] Problems with unsigned integers

[Loptr Chaote]

Hello everyone! 

I'm having problems with signed/unsigned (32bit) integers in python.
Example code:

  seq = 0L
  seq = socket.ntohl(struct.unpack("L", data[38:42])[0])
  print seq

This sometimes produces a negative output, how is that possible since
I booth initialized seq with "0L" and also specified "L" in unpack()?
