Try this (Python 3, in which strings are Unicode):
>>> import struct
 >>> # For a little-endian integer
>>> struct.unpack("<I", "abcd".encode("latin-1"))[0]
1684234849
>>> hex(_)
'0x64636261'

or this (Python 2, in which strings are bytestrings):
 >>> import struct
 >>> # For a little-endian integer
 >>> struct.unpack("<I", "abcd")[0]
1684234849
 >>> hex(_)
'0x64636261'
