[New-bugs-announce] [issue38752] __init__ taking out of context variables

[Sebastian Bevc]

New submission from Sebastian Bevc <sebastian.bevc at gmail.com>:

Hello,

This is my first bug report. While doing some homework i came to realize that the __init__ of a class was taking out of context variables.

class Foo(object):
  def __init__(self, attr1):
    self.out_of_context = out_of_context


# Raises NameError as it is expected
foo = Foo('some attr')

# 'bar' is bounded to 'out_of_context' although it was initialized
# with value 'some value'
out_of_context = 'bar'
foo = Foo('some value')
print(foo.out_of_context')  # prints 'bar'
