Python Forum

First of all, I am new to python.
I have arduino connected to my PC. I have a few button interfaced with my arduino. When a button is pressed I want an image to be displayed on my windows PC. Here's my arduino code. At the moment I am only testing button on pin 9, as you can see in code.

#define data0 5
#define data1 6
#define data2 7
#define data3 8
#define data4 9

int data[5];



void setup() {
// put your setup code here, to run once:
pinMode(data0, INPUT);
pinMode(data1, INPUT);
pinMode(data2, INPUT);
pinMode(data3, INPUT);
pinMode(data4, INPUT);
Serial.begin(9600);
}

void loop() {
// put your main code here, to run repeatedly:

data[0] = digitalRead(data0);
data[1] = digitalRead(data1);
data[2] = digitalRead(data2);
data[3] = digitalRead(data3);
data[4] = digitalRead(data4);
if(data[4]==1){
Serial.println(1);
}
delay(100);
}

And here's my python code

import serial
import time

ser = serial.Serial('COM6', baudrate = 9600, timeout =1)

def showPIL(pilImage):
    root = tkinter.Tk()
    w, h = root.winfo_screenwidth(), root.winfo_screenheight()
    root.overrideredirect(1)
    root.geometry("%dx%d+0+0" % (w, h))
    root.focus_set()    
    root.bind("<Escape>", lambda e: (e.widget.withdraw(), e.widget.quit()))
    canvas = tkinter.Canvas(root,width=w,height=h)
    canvas.pack()
    canvas.configure(background='black')
    imgWidth, imgHeight = pilImage.size
    if imgWidth > w or imgHeight > h:
        ratio = min(w/imgWidth, h/imgHeight)
        imgWidth = int(imgWidth*ratio)
        imgHeight = int(imgHeight*ratio)
        pilImage = pilImage.resize((imgWidth,imgHeight), Image.ANTIALIAS)
    image = ImageTk.PhotoImage(pilImage)
    imagesprite = canvas.create_image(w/2,h/2,image=image)
    root.mainloop()


while 1:
    arduinoData = ser.readline().decode('ascii')
    if arduinoData == 49:
        pilImage = Image.open("sample.jpg")
        showPIL(pilImage)

Above python function to display the image works, I have tested it. The code to receive the arduino data also works fine, because when I do

print(arduinoData)

I can see the data. But when I run the above code and press the button, nothing happens.

Is arduinoData equal to 49?
