+### position-on-screen-and-in-parent.py
+Code shows `canvas` position on screen and in parent `Frame` (not in `root`).
+
+![#1](images/screenshot.png?raw=true)   
+
+
+Example result
+
+```
+--- before mainloop start ---
+
+  root.geometry: 1x1+0+0
+canvas.geometry: 1x1+0+0
+canvas.width : 1
+canvas.height: 1
+canvas.x: 0
+canvas.y: 0
+canvas.rootx: 0
+canvas.rooty: 0
+
+--- after mainloop start ---
+
+  root.geometry: 380x303+770+462
+canvas.geometry: 380x267+0+18
+canvas.width : 380
+canvas.height: 267
+canvas.x: 0
+canvas.y: 18
+canvas.rootx: 770
+canvas.rooty: 498
+```
+
+
+`Canvas` position on screen is `(770, 498)`, in `Frame` is `(0, 18)` but in `root` is `(0, 32)`   
+(root position on screen is `(770, 462)` so `(770, 498)` minus `(770, 462)` gives `(0, 32)`)
