Surprised by the command "del"

I'm reading the docs and at 5.2 the del statement is discussed. At first, i thought i've found a typo but as i tried that myself, it turns it actually does work so. a = ["alpha", "beta", "gamma"] del a[2:2] a Now, i expected the result to be that the "beta" element has been removed. Obviou

Quit-command not quiting

I entered the code from tkinter.pdf, section 2 but for reason, the application doesn't close as i press the quit-button. The wondow itself vanishes if i click the cross in the upper-right corner but pressing the quit-button only makes it "pressed". Then, the program freezes. This is the code.

I'm disliking the size of my frame and also i'm disappointed regarding it's location. So, i wish to change them. At this link http://infohost.nmt.edu/tcc/help/pubs/tkinter/frame.html the frame object is discussed but as far i can tell, there are only suggestions regarding what to put in the cons
