How to display Arduino serial data to python gui?

Question

I am working on project in which I am getting data from Arduino serially and accessing them into Python.To access data from arduino I am using pyserial. After that I have to display that data on Python GUI. How can I do this?

I am getting this data in Arduino Serial Monitor....

And using pyserial I am getting this data as python output...

In python I have used this code to get Serial data....

import serial
arduino = serial.Serial('COM5', 9600, timeout = .1)
arduino_data = [] # declare a list
while True:
    data = arduino.readline()
    if data:
        arduino_data.append(float(data)) # Append a data to your declared list
        print arduino_data

What is the relevance of pyserial and arduino in your question, when it seems to be all about how to display data in python gui? Could you be a little more specific on how you want to display your data? Could you provide a data example? note: edit your question to add relevant information, don't use comments for that. — Patrick Trentin

Great edit, upvoted. Now, what is the end result that you want to achieve? do you simply want to plot a live graph or you want an entire application around it? — Patrick Trentin

@PatrickTrentin..Thanks for upvoting...Not live graph but can say entire application around it,i.e. just create a windows that can display serial data that I got in python shell.which I have displayed in myquestion as pyserial output. — karanrp

Ok, then I think I am not able to help you on this. There are similar projects from which you could take inspiration, though. See this, this, this and this — Patrick Trentin

import serial
arduino = serial.Serial('COM3', 9600, timeout = .1)
arduino_data = [] # declare a list
i=0;
while i<5:
    data = arduino.readline()
    if data:
        #arduino_data.append(data) # Append a data to your declared list
        print data
        i=i+1;


#try this code mate, i am beginner but did this for you i think i will work for you please
