I usually use golang for implementations and I need to implement a python project. I have the following instructions (Golang)

import "encoding/binary"
arBytes := make([]byte, 16)
    _, err := rand.Read(arBytes)
    if err != nil {
        return false, err
    }
a0 = binary.LittleEndian.Uint64(arBytes[0:8])

I need to write the python's version for these instructions but i do not found any way to create an array of little Endian from Uint64. Is there any available solution that can help!

CodePudding user response：

The equivalent Python program would be as follows.

• Use secrets.token_bytes(16) to generate 16 random bytes, like rand.Read(arBytes) would.
• Then use int.from_bytes(..., "little") on that byte array to interpret the bytes as a little-endian integer. from_bytes defaults to unsigned values.

import secrets
b = secrets.token_bytes(16)
val = int.from_bytes(b[:8], "little")
