I don't understand that sentence. If you press the button the label should
disappear. When you press it again it should become visible again.
I added some noise to your initial script and saved the placement state:
import sys
import Tkinter as tk
def toggle():
if mylabel.visible:
btnToggle["text"] = "Show Example"
print "Now you don't"
mylabel.place_forget()
else:
mylabel.place(mylabel.pi)
print "Now you see it"
btnToggle["text"] = "Hide Example"
mylabel.visible = not mylabel.visible
root = tk.Tk()
print "TkVersion", tk.TkVersion
print "TclVersion", tk.TclVersion
print "Python version", sys.version_info
mylabel = tk.Label(text="Example")
mylabel.visible = True
mylabel.place(x=20, y=50)
mylabel.pi = mylabel.place_info()
btnToggle = tk.Button(text="Hide Example", command=toggle)
btnToggle.place(x=70, y=150)
root.mainloop()
That does what it's expected to do over here.
