Steven's already asked what error, and is it compile time or runtime. I'll add
foo.py:
constant x = 12
bar.py
import foo
foo.x = 19
You can only detect this at runtime.
baz.py
import foo
name = 'x'
setattr(foo, name, 22)
You can only detect this at runtime.
Also,
if some_condition:
constant a = 1
else:
a = 2
a = 3
Is this allowed? Is a constant?
What about
for i in range(10):
constant a = []
Is this allowed, or is it 10 rebindings of a?
for i in range(10):
constant a = [i]
What about this? What is a "literal" anyway? You've used lists in
examples (when discussing mutability) but list displays aren't
actually literals.
Lots of questions. I'm sure it's possible to answer them. But as the
proposer, *you* need to give the answers (or at least give a complete
and precise enough specification that people can deduce the answers).
At the moment, everyone is just guessing.
