现在我们将做一批练习,在练习的过程中你需要键入代码,并且让它们运行起来。我不会解释太多,因为这节的内容都是以前熟悉过的。这节练习的目的是巩固你学到的东西。我们几个练习后再见。不要跳过这些习题。不要复制粘贴!
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | 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
