Yes, sort of. Bind two names to the same mutable object:
py> x = ["Something mutable"]
py> y = x
py> y.append("this way comes.")
py> print x
['Something mutable', 'this way comes.']
Note that this only works with mutable objects like lists and dicts, and
is a side effect of mutability, rather than a deliberate "alias".
In general, you can bind multiple names to the same object. The one liner
x = y = 1
is the same as the two liner
x = 1
y = x
Both create two names, x and y, and sets them both to the same int 1.
Because ints are immutable, if you rebind one name, the other one will
NOT change:
py> x += 1
py> print x, y
2, 1
