习题 7:

print "Mary had a little lamb." print "Its fleece was white as %s." % 'snow' print "And everywhere that Mary went." print "." * 10 # what'd that do? end1 = "C" end2 = "h" end3 = "e" end4 = "e" end5 = "s" end6 = "e" end7 = "B" end8 = "u" end9 = "r" end10 = "g" end11 = "e" end12 = "r" # watch that comma at the end. try removing it to see what happens print end1 + end2 + end3 + end4 + end5 + end6, print end7 + end8 + end9 + end10 + end11 + end12

想了想为什么作者不放答案图，因为这个过程他写出来了，那就偷懒不放了。

这题亮点在那10个逗号。
