I tried a simplified version of this in the Idle shell. Idle displays 
call tips if you pause after typing '('.  Unlike .pack and .grid, .place 
apparently does not automatically put the widget in its master. At least 
this is true when placing in a canvas. You need an 'in_' argument (the 
'_' is needed to not be the keyword 'in').  Try

canvas1.pack() #don't use place unless really needed.
...
myButton1.place(in_=canvas1, x=500, y=300)
