Python中关于input和raw_input的比较

#input假设用户输入的是合法的Python表达式

>>> name = input("what is your name?")

what is your name?ZJ

Traceback (most recent call last):

 File "<stdin>", line 1, in <module>

 File "<string>", line 1, in <module>

NameError: name 'ZJ' is not defined

#于是，必须这么使用，输入Python格式的字符串"ZJ"

>>> name = input("what is your name?")

what is your name? "ZJ"

>>> print name

ZJ

>>>

#raw_input会把所有输入当作原始数据(raw data)，然后将其放入字符串中

>>> name = raw_input("what is your name?")

what is your name?ZJ

>>> print name

ZJ

>>>
