Hello,
    I can't seem to find this in the documentation, is there a way to 
clear a variable.  For example I have an application that opens 
displays a bunch of images, they can be big memory hogs. When I'm not 
showing them I'd like to clear out those variables, instead of having 
to close down my program and start over.  I know matlab has a command 
"clear var" which will do exactly that.

del(obj)

If you are the only user of "obj", this'll do the trick. (del tries 
to be polite and not pull the rug out from under other users).

obj can be nearly anything, such as an array or any other object you 
created. del can also be used to delete specific elements of lists 
and dictionaries, i.e.:
del(adict[akey])
del(alist[ind1:ind2])

I hope this help.
