[Tutor] is this a bug global i ???

[Alan G]

class A:
  def __init__(self,j):
    self.j = j

  def something(self):
    print self.j
    print i            # PROBLEM is here there is no var i in class A
but it works ???

if __name__ == '__main__':
  i = 10
  a = A(5)
  a.something()

> I don't define global i but it will takes var i from outside of
class A.
> Can somebody explain this ???

You only need to declare global if you are modifying data if you only
read it there is no need for explicit global statements.
