how to display the values in Entry in tkinter?

I wanted to know how to display the integer and double values in the text box. As I have to calculate mean values of an image, and I want those values to be displayed in the text box in the GUI.

When I tried with my code I got an error:

AttributeError: numpy.ndarray object has no attribute set

This is because I'm using .set() for ndarray. But without .set() how to send the values to the textbox?

Here's my code snippet:

def open():
    path=tkFileDialog.askopenfilename(filetypes=[("Image File",'.jpg')])
    blue, green, red = cv2.split(re_img)
    total = re_img.size
    B = sum(blue) / total
    G = sum(green) / total
    R = sum(red) / total
    B_mean1.append(B)
    G_mean1.append(G)
    R_mean1.append(R)

    blue.set(B_mean)

root = Tk()
blue_label = Label(app,text = 'Blue Mean')
blue_label.place(x = 850,y = 140)
blue = IntVar(None)
blue_text = Entry(app,textvariable = blue)
blue_text.place(x = 1000,y = 140)
button = Button(app, text='Select an Image',command = open)
button.pack(padx = 1, pady = 1,anchor='ne')
button.place( x = 650, y = 60)
root.mainloop()

I have no idea whether my coding is wrong or not. And these mean values are being stored in list. Any suggestions for this problem?

Thanks for your support!

There's nothing on numpy.ndarray called "set":

http://docs.scipy.org/doc/numpy/reference/generated/numpy.ndarray.html

Take a good look at this reference and figure out how to apply B_mean to blue.

blue is a local name in your function, shadowing your global IntVar reference blue.

Rename one or the other.
