As Peter suggested, use struct.unpack with the appropriate endianness, e.g.

>>> import struct
>>> length = '\x01\x00\x00\x00'
>>> # convert 'length' to signed integer (big-endian)
>>> unpacked = struct.unpack('>i', length)[0]  # unpack returns a tuple
>>> unpacked
16777216
>>> # convert 'length' to signed integer (little-endian)
>>> unpacked = struct.unpack('i', length)[0]   # or,  fmt = '<i'
>>> unpacked
1
