i just changed these things to fix the scroll bar height.
Using ipady to increase the height of a scrollbar.

Result = Text(root,height=20,width=69)
Result.grid(rowspan=10,columnspan=40,sticky='W',padx=5)
Scroll = Scrollbar(root,command=Result.yview)
Scroll.grid(row=1,column=6,ipady=135)
Result.config(yscrollcommand=Scroll.set)
