   I got some "escape sequence" warnings, plus, eventually I got a runtime error. However, I

   was able to decode by using the interactive "python" command line and typed in several lines of

   code at the >>> prompt. Once I get some feedback I'll decode more secret texts. Thank you, Stacy.

   'Tyger Tyger, burning bright, In the forests of the night; What imortal hand or eye, Could frame thy fearful symetry?' In what distant deeps or skies. Burnt the fire of thine eyes?On what wings dare he aspire?What the hand, dare seize the fire? And what shoulder, & what art,Could twist the sinews of thy heart?And when thy heart began to beat.What dread hand? & what dread feet? What the hamer? what the chain,In what furnace was thy brain?What the anvil? what dread grasp.Dare its deadly terrors clasp? When the stars threw down their spears And water'd heaven with their tears:Did he smile his work to see?Did he who made the Lamb make thee? Tyger Tyger burning bright,In the forests of the night:What imortal hand or eye,Dare frame thy fearful symetry?
