Document Summary

Beside each code fragment below, show the output that it would create. If it would generate an error say so, and give the reason why. [1 mark] print 12 - 4. 0*3 + 2. [1 mark] z = 3 * "blah" print z + str(3) + "blah" [1 mark] ratio = 1. 5433333 print "ratio is %. 4f", % (ratio) [1 mark] s = "abc" for c in s: piece = "" for i in range(4): piece = c * i + ":" print piece. [1 mark] s = "abc" for i in range(2): piece = "" for c in s: piece = piece + str(i) + c * i print piece. Solution: (a) 3 (b) 2. 0 or 2 and some indication that it"s a float. (c) blahblahblah3blah (d) ratio is 1. 453 (e) aaa: bbb: ccc: (f) Each of the code sequences below runs without error. The next page is provided for your rough work.
