pack() retirns None, YOu *must* use two steps:

text = Text()
text.pack()

Because your text variable contains None, which doesn't support get...

Don't worry, its one of the most common Tkinter mistakes and
bites most folks at some stage...

pack() doesn't return a value. You have to do
text = Text(root)
text.pack()
I've been bitten by this one more than once myself :-(

button=Button(root,text="Click here!!",command=p_text).pack()
root.mainloop()
I get an error that says that nontype object has no attribute 'get'...
