I cannot set break point inside the editor of IDLE.

[lilzz]

I searched the net and read some message saying by highlighting the line of code inside the editor of IDLE,and right clicked it and there's option for set breakpoint.

But I right clicked it no option pop up. I also search top action menu bar, I don't see set break point option.

Before you can set breakpoints, you need to open your code in IDLE and start the debugger (from the main IDLE Window "Debug" menu item). Once the debugger is running, just right click a line of your code to switch on / off breakpoints.
