I think you should post this in python-dev and you might get answers with
rigorous definitions.
Here is my short snippet which shows a behavior which does not indicate a
dynamic binding nature.
# example.py
x = 10
y = lambda: x
def f():
x = 20 # This is not rebinding. It is creating a new local variable by
name x
# But we are referring to x in y function call, so for the
definition of dynamic binding (?)
# should y() see x defined in the local scope instead of the
previously assigned value.
print(y())
return y()
x = 30 # This is rebinding in the same scope.
print(f())
$ python example.py
30
30
