Ok, for line 2, run this ;-)

class ThisIs:
    avariable = 'a'
    def amethod(self):
        return 'b'
    def silly(self):
        return 'heh'
    silly = property(silly)

thisis = ThisIs()
print thisis.avariable
print thisis.amethod()
print thisis.silly
import sys
class L2(list):
    def write(self, s): self.append(s)
sys.stdout = L2()
import this
L2 = ''.join(sys.stdout).splitlines()[2]
sys.stdout = sys.__stdout__
print "Read line 2."
print '... which is:', L2
