input 与raw_input的区别

input只能输入数字

raw_input 既可以输入数字也可以输入字符串

>>> input("input you name:")
input you name:carrie
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 1, in <module>
NameError: name 'carrie' is not defined


>>> input("input you name:")
input you name:11
11

>>> raw_input("input you name:")
input you name:carrie
'carrie'

>>> raw_input("input you name:")
input you name:11
'11'
