Yup. I think some people are getting confused over assignment to simple variables as opposed to more complex expressions on the LHS of assignments in Python. For example, given

    a = [1, 2, 3, 4]

compare the different effects of

    b = a
    b = a[:]
    b[:] = a # assuming b already has an appropriate initial value

not to mention other possibilities...
