New submission from Andrej Klychin <andy...@bk.ru>:
I'm not sure is it a bug or a fecature of comprehensions or eval, but
intuitively it seems like it should work.
def foo(baz):
return eval("[baz for _ in range(10)]")
foo(3)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 2, in foo
File "<string>", line 1, in <module>
File "<string>", line 1, in <listcomp>
NameError: name 'baz' is not defined
def bar(baz):
return eval("{i: baz for i in range(10)}")
bar(3)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 2, in bar
File "<string>", line 1, in <module>
File "<string>", line 1, in <dictcomp>
NameError: name 'baz' is not defined
