The word "variable" brings implications and assumptions that get
people into trouble in Python.  Python doesn't have variables.
It has objects, and you can assign names to objects -- like sticky
notes, as someone in this newsgroup helpfully pointed out long ago.

This way of thinking is significantly different from the familiar
"variable" mind-set of C, but looks similar enough to produce some 
confusion.  For me, the sticky-note analogy helped a lot, and in a
few days many things made more sense.
