Convert code from arduino to python

Question

Can anyone help me in translating the below Arduino code into python code?

#define BUFFLEN 3

byte buffer[] = { 0x05, 0x0D, 0x02, 0xFF, 0x10, 0xAA }

for (byte i=0; i < BUFFLEN; i++) {

    val = analogRead(A0);

    val = constrain(val,0,1023);

    buffer[i*2] = (byte)(i<<2) | highByte(val);

    buffer[i*2+1] = lowByte(val);

}

Thank you

You could utilize the pyserial library to catch the data by means of the serial port at that point process the information using python, in which case the accompanying code would do:

import serial

import struct

ser = serial.Serial('COM6',9600) #put the port number and the communication rate

BUFFLEN = 3 #constant

buffer = [ 0x05, 0x0D, 0x02, 0xFF, 0x10, 0xAA ]   #array

i=0  #initialize control variable

def clamp(n, minn, maxn):

    return max(min(maxn, n), minn)

while (i < BUFFLEN):

    val = ser.read()

    val = clamp(val,0,1023)

    buffer[i*2] = (i<<2) or struct.pack('<h', val)

    buffer[i*2+1] = struct.pack('>h', val)

    i+=1    #increment

However, make sure to catch and print the information to serial from the Arduino IDE
