Transfering float data between PC and Teensy

ran the following python code on a Win10 PC
it transmits bytes of binary data and then displays text received

import numpy as np
import serial

data = np.array([1,0.5,3.14159, 2.718281828]).astype(np.float32) #this is test data, my real data is a lot bigger
print(data)
S = serial.Serial(port='COM6',  baudrate=115200, timeout=1)
S.write(data.tobytes())
print(data.tobytes())
#x=S.read(8)
print("reading serial");
while 1:
    try:
        # serial data received?  if so read byte and print it
        while S.in_waiting > 0:
            char = S.read()
            print(str(char,'ASCII'),end='')
    except:
        pass

ran following code on an ESP32
it receives 8 bytes of data, copies the bytes into float variables and displays the results
EDITED: to use a float array for results

void setup() {
  Serial.begin(115200);
  while (!Serial.available())
    ;
  byte buffer[100];
  int len = Serial.readBytes(buffer, 100);

  Serial.print(len);
   Serial.print(" bytes received "); for (int i = 0; i < len; i++) {
    Serial.print(" 0x");
    Serial.print(buffer[i], HEX);
  }
  Serial.println();
  Serial.print("sizeof(float) ");
  Serial.println(sizeof(float));
  // copy bytes into float variables and display
  float data[10];
  memcpy(data, buffer, len);
  Serial.print("data = ");
  for (int i = 0; i < len / sizeof(float); i++) {
    Serial.print(" ");
    Serial.print(data[i]);
  }
}

void loop() {}

python console displays

binary data received OK and float values 1.0 and 0.5 are correct

I need help(python for arduino
