I have an little endian list value in python, I get with serial line.
I get this value as a byte like this:
[0, 0, 52, 66]
How can I convert this 4 byte (little endian) value to float ?

You should take a look at the struct modulefskj– fskj2021-11-24 13:54:52 +00:00Commented Nov 24, 2021 at 13:54

If the float is in IEEE754 format (which it very likely is), you can convert your list of numbers to a byte array and then use struct.unpack to unpack it:
import struct
ba = bytes([0, 0, 52, 66])
print(struct.unpack('<f', ba)[0]) # prints 45.0
