[issue24800] Incorrect handling of local variables in comprehensions with exec()

[R. David Murray]

R. David Murray added the comment:

exec is subtle.  See the explanation linked from issue 23087, which while not *exactly* on point explains the underlying problem (a comprehension is a new scope, and exec can't reach an intermediate scope the way a compiled function can).

As far as the difference from 2.7 goes, the scoping rules for comprehensions changed in python3: the variable you are concerned with is now part of the local scope.
