Christian & Others:

Thanks for your attention to this matter.
My code now look like this:

from Tkinter import *


def butContinue():
    dbUser = entryName.get()
    pWord =  entryPWord.get()
    print dbUser
    print pWord
    root1.quit()


dbUser = ""
pWord  = ""
root1 = Tk()
##root1.geometry("500x250")


lblTop = Label(root1, text= '      Enter Values Below', font="Helvetica 14").grid(row=0, column=0, columnspan=2 , pady=5)
##lblTop.pack(side = TOP)

lblDB = Label(root1,    text= 'Weight').grid(row=1, column=0 )
lblPWord = Label(root1, text= 'Height').grid(row=2,column=0)
entryName = Entry(root1)
entryName.grid(row=1, column=1, pady=5)

entryPWord = Entry(root1)
entryPWord.grid(row=2, column=1, pady = 5)

butGo  =  Button(root1, text="   Continue "  , command=butContinue ).grid(row=3, column=1, sticky=W, pady=10)


root1.mainloop()

print "After the MainLoop"
print dbUser
print pWord

After I type in the text Weight and Height
No error are reported and output looks like this:

Weight
Height
After the MainLoop


Question:  
Why did this code not cause Weight and Height to print again.

print "After the MainLoop"
print dbUser
print pWord

Thanks in advance.
