python input 與raw_input函數的區別

   之前沒有深刻考慮過raw_input與input函數的區別，因此一直比較困惑，今天測試以後，有了較爲深刻了解，記錄以下

>>> user = raw_input("Enter your name:")
Enter your name:scr
>>> user
'scr'
>>> user = raw_input("Enter your name:")
Enter your name:123
>>> user
'123'
>>> user = input("Enter your name,please!")
Enter your name,please!4
>>> user
4
>>> user = input("Enter your name,please!")
Enter your name,please!"scr"
>>> user
'scr'
>>> user = input("Enter your name,please!")
Enter your name,please!scr


Traceback (most recent call last):
  File "<pyshell#67>", line 1, in <module>
    user = input("Enter your name,please!")
  File "<string>", line 1, in <module>
NameError: name 'scr' is not defined
>>> 

總結：raw_input更符合用戶輸入的習慣，把任何用戶輸入都轉換成字符串存儲，在須要其它類型的數據時，調用相應的函數進行轉換

input用戶輸入什麼就存儲什麼，因此用戶輸入必須符合python語法要求，不然會出錯，例如

>>> user = input("Enter your name,please!")
Enter your name,please!scr


Traceback (most recent call last):
  File "<pyshell#67>", line 1, in <module>
    user = input("Enter your name,please!")
  File "<string>", line 1, in <module>
NameError: name 'scr' is not defined
>>>
