New submission from Ákos Tompos <akos.br...@gmail.com>:
The following code does work on python 2.7 but fails on python 3.7. The code
seems correct.
class A:
class B:
def __init__(self, param):
self.param = param
l = [B(i) for i in range(10)]
The result on:
3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 22:22:05) [MSC v.1916 64 bit (AMD64)]
Traceback (most recent call last):
File "test.py", line 6, in <module>
class A:
File "test.py", line 11, in A
l = [B(i) for i in range(10)]
File "test.py", line 11, in <listcomp>
l = [B(i) for i in range(10)]
NameError: name 'B' is not defined
B can be accessed if not inside a generator expression
