在Python 2.7中将字符串更改为字节类型 [英] Changing string to byte type in Python 2.7

问题描述

在python 3.2中，我可以轻松更改对象的类型.例如:

In python 3.2, i can change the type of an object easily. For example :

x=0
print(type (x))
x=bytes(0)
print(type (x))

它会给我这个:

<class 'int'>
<class 'bytes'>

但是，在python 2.7中，似乎我无法使用相同的方法来执行此操作.如果我执行相同的代码，它将给我:

But, in python 2.7, it seems that i can't use the same way to do it. If i do the same code, it give me this :

<type 'int'>
<type 'str'>

如何将类型更改为字节类型?

What can i do to change the type into a bytes type?

推荐答案

如何将类型更改为字节类型?

您不能，在Python 2.7中没有像字节"这样的类型.

You can't, there is no such type as 'bytes' in Python 2.7.
