Nick Coghlan added the comment: With the fact that the existence of "Python without closures" predates Python 2.2, this now reads like a straight up compiler bug to me. Compare the behaviour with no local assignment in the class body: >>> def f(): ... n = 1 ... class C: ... pri

Armin Rigo added the comment: Terry: I meant exactly what I wrote, and not some unrelated examples: def f(): n = 1 class A: n = n doesn't work, but the same two lines ("n = 1"; "class A: n = n") work if written at module level instead of in a function. --

Terry J. Reedy added the comment: As near as I can tell, "class A: n = n" currently works the same at module and nested scope, the latter with or without nonlocal n. >>> class A: n=n [...] NameError: name 'n' is not defined >>> def f(): class A: n=n >>> f() [...] NameError: na

New submission from Armin Rigo: This is a repeat of the old issue 532860: "NameError assigning to class in a func". It is about class statements' variable lookups, which has different behavior at module level or in a nested scope: def f(n): class A: n = n # doesn't work, tries
