class f(object):
    def __init__(self): 
        self.inContext = False
    def __enter__(self): 
        self.inContext = True
        return self
    def __exit__(self,a,b,c):
        self.inContext = False
        return None

x = f()
print 'not within:', x.inContext
with f() as h:
    print 'within:', h.inContext
