Writing variables to a hex file in Python

Question

So, I have got a float value: -1.0f, or something. And how could I write it into a file in hexadecimal format in Python? I mean that we open the file in notepad, we won't see the hexadecimal values, just the ASCII code.

Answer 1

In Python 3:

>>> import struct
>>> "".join("{0:02X}".format(b) for b in struct.pack(">f", -1.0))
'BF800000'

In Python 2:

>>> import struct
>>> "".join("{0:02X}".format(ord(b)) for b in struct.pack(">f", -1.0))
'BF800000'
