    how to execute python code with tkinter user input

    when user input in this tkinter code (tkintt.py) and click submit button, i want the program execute k-medoids code (example.py) based on how many cluster that user input but it gets some errors. could you help me?

    tkintt.py

    Code:
    import Tkinter
from _tkinter import *
root = Tkinter.Tk()

label1 = Tkinter.Label(text = " enter cluster : ")
label1.pack()
clvar = Tkinter.IntVar()
cluster = Tkinter.Entry(bd = 5)
clvar = cluster.get()
cluster.pack()

def open1():
  print ("K-MEDOIDS CLUSTERING")
  execfile('example.py')

button_1 = Tkinter.Button(text = "SUBMIT", command = open1)
button_1.pack()
root.mainloop()
    example.py

    Code:
    from k_medoids import KMedoids
import numpy as np
import matplotlib.pyplot as plt


def example_distance_func(data1, data2):
   '''example distance function'''
   return np.sqrt(np.sum((data1 - data2)**2))

if __name__ == '__main__':
   X = np.random.normal(0,3,(500,2))
   model = KMedoids(n_clusters= cluster, dist_func=example_distance_func)
   model.fit(X, plotit=True, verbose=True)
   plt.show()


    error :

      Nothing in example.py will execute when called from another program. If __name__ == "__main__" will only execute when the program is run from the command line. You would have to do something like call example_distanc e_func from the calling program. See ghostdog74's reply here https://bytes.com/topic/python/answe...-python-script To receive the data returned by example_distanc e_func use subprocess.chec k_output() https://pymotw.com/2/subprocess/inde...ule-subprocess
