executes the command data[j] = factor. We have discussed that numeric

types are immutable, and that use of the = operator in this context causes

the creation of a new instance (not the mutation of an existing instance).

How is it still possible, then, that our implementation of scale changes the

actual parameter sent by the caller?

Q148: Had we implemented the scale function (page 25) as follows, does it work

properly?

def scale(data, factor):

for val in data:

val = factor

Explain why or why not.
