I think it helps understanding if you translate the above to
A = [1,2,3]
B = 1
def f(a):
... for x in a:
... yield x+B
...
g = f(A)
A = [4,5,6]
B = 10
print list(g)
[11, 12, 13]
This is not altogether unintuitive, but I think I would prefer if it
worked
like
A = [1,2,3]
B = 1
def f(a, b):
... for x in a:
... yield x+b
...
g = f(A, B)
A = [4,5,6]
B = 10
list(g)
[2, 3, 4]
i. e. every name were bound early. Of course this wouldn't help with
locals() which would still be called in different scopes.
Yep -- although I would like all names were late bound instead. But as I
posted in another message, in this case "practicality beat purity" and a
special case was made for the leftmost iterable.
