The struct module provides a portable way to convert a float to and from a
sequence of bytes.
The binascii modules provides tools for converting a sequence of bytes to and
from a representation as a hex string.
>>> import struct, binascii
>>> binascii.hexlify(struct.pack('>f', 3.1415926535))
'40490fdb'
>>> struct.unpack('>f', binascii.unhexlify(_))[0]
3.1415927410125732
Writing to a file is accomplished with the open() function and the file.write()
method:
f = open('mydata.hex', 'w')
f.write('40490fdb')
f.close()
