for just a few values, you can use the struct module:
>>> struct.unpack("f", "\x00\x38\x93\x45")
(4711.0,)
for arrays of floats, use the array module. it returns an
array object, which behaves pretty much like any other
sequence:
>>> array.array("f", "\x00\x38\x93\x45"*5)
array('f', [4711.0, 4711.0, 4711.0, 4711.0, 4711.0])
