import os

def submitData():
global tag
global tagBox
if (tagBox is not None):
tag = tagBox.get("1.0","end-1c")
print ("!!SUCESS!! tag -->", tag)
else:
print ("!!ERROR!! Tag is None")

gui = Tk()
gui.title("GUI")
gui.geometry('250x300')

tag = "NA"
tagBoxLabel = Label(gui, text = "Tag: ").grid(column=0, row=5, pady=30, 
sticky="EN")
