Question

I have an array of float that I need to send over TCP/IP, the protocol is text based so basically I cannot send directly binary.

What Im trying to do is to convert the Float values to 4 Ord

So ex:

“”” Initialize the float “””

a = 3.14159

“”” Final result should be a string containing the 4 Ord, 1 for each byte the of the float value: “””

b = “\123\23\22\245”

Anybody can help me with this?

TIA!

Answer 1

>>> import struct
>>> struct.pack("!f",3.14159)
b'@I\x0f\xd0'

not sure where you arrived at "\123\23\22\245"

If you wish to convert a list of floats

>>> a=[3.14159, 2.71828]
>>> struct.pack("!{}f".format(len(a)), *a)

will give you a single string. No need for an explicit loop and join
