exercise 12 提示

age = raw_input("How old are you? ")
height = raw_input("How tall are you? ")
weight = raw_input("How much do you weigh? ")

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

$ python ex12.py
How old are you?  38
How tall are you?  6'2"
How much do you weigh?  180lbs
So, you're '38' old, '6\'2"' tall and '180lbs' heavy.  # 使用%r 會有引號

pydoc ？？？？

ex12
1.print xxxxxxx ,
後面加 逗號 表示下一行的內容與print顯示在同一行
我們在每行後加了逗號，這樣就不會換行等待輸入

2.
version1
How tall are you?
6'2
So, you're '22' old, "6'2" tall and '110' heavy.

version2
How tall are you?
6'2"
So, you're '22' old, '6\'2"' tall and '110' heavy.

3.
age = raw_input("How old are you?")
等價於
print "How old are you?",  
age = raw_input() 

4.
x = int(raw_input())
將輸入的字符串轉換成int型變量 就可以用作數學計算了

5. pydoc don't understand!!!!
