ex11開始接觸人機(jī)互動(dòng)模式，我也喜歡叫它黑盒模式，一端有input一端有output，這也是軟件的基礎(chǔ)模型，想想我們學(xué)習(xí)編程的目的是什么，就是想讓我們寫出的程序處理我們想要它得理的事情，并把結(jié)果返給我們看。
raw_input()就是讓你input的接口，而且可以帶提示的，例如我想寫一段代碼，但是要提醒你輸入指定內(nèi)容，raw_input("your name? ")，但我測試后有一個(gè)地方要注意，就是所有通過這個(gè)raw_input()輸入都是字符串格式(string)
在網(wǎng)上搜了一些關(guān)于格式的一些代碼
- 直接字符串的就不寫了
- 輸入整數(shù)
nAge = int(raw_input("input your age plz:\n"))
if nAge > 0 and nAge < 120:
print 'thanks!'
else:
print 'bad age'
print 'your age is %d\n' % nAge
```
- 輸入浮點(diǎn)數(shù)型
fWeight = 0.0
fWeight = float(raw_input("input your weight\n"))
print 'your weight is %f' % fWeight
暫且先寫這兩個(gè)例子，記住輸入的是string 就行了，想要把數(shù)據(jù)處理，就要再轉(zhuǎn)換
還有個(gè)知識(shí)點(diǎn)就是pydoc相當(dāng)于幫助文檔，在window下powershell中輸入python python -m pydoc raw_input，就能查看raw_input相關(guān)內(nèi)容的幫助文檔
把這兩課的代碼貼上
ex11
#coding=utf-8
print "How old are you?",
age = raw_input()
print "How tall are you?",
height = raw_input()
print "How much do you weight?",
weight = raw_input()
print "So, you're %r old, %r tall and %r heavey." % (
age, height, weight)
ex12
#coding=utf-8
age = raw_input("How old are you? ")
height = raw_input("How tall are you? ")
weight = raw_input("How much do you weight?")
print "So, you're %r old, %r tall and %r heavey." % (
age, height, weight)
比較一下兩者的區(qū)別
