AARHG! I am always frustrated by "it doesn't work" This gives us 
insufficient information. Please always present us with the specific 
diagnostic.

 "it doesn't work"
 ... Could mean del raises an exception..
 ... Could mean that the key is still in the dictionary after the del.
 ... Could mean that the key is still in the dictionary after you pickle 
dump then open load.
 ... Could mean you see "...Has been removed"
 ... Could mean you see "...That word is not in the dictionary""

More information, please.
