习题11：提问

print "How old are you?",age = raw_input()

print "How tall are you?",height = raw_input()

print "How much do you weigh?",weight = raw_input()

print "So, you're %r old, %r tall and %r heavy." % (age, height, weight)

每行 print 后面加了个逗号 (comma) ，这样的话 print 就不会输出新行符而结束这一行跑到下一行去

我试着把raw_input( ),改成input( )

结果发现：

 you're '20' old, '170' tall and '55' heavy.

变成了

So, you're 20 old, 170 tall and 55 heavy.
