在python 2和3中使用input/raw_input [英] Use of input/raw_input in python 2 and 3

问题描述

我想设置一个带有以下问题的用户提示:

I would like to set a user prompt with the following question:

save_flag未设置为1；数据将不会保存.按Enter键继续.

save_flag is not set to 1; data will not be saved. Press enter to continue.

input()在python3中有效，但在python2中无效. raw_input()在python2中有效，但在python3中无效.有没有一种方法可以使代码与python 2和python 3兼容?

input() works in python3 but not python2. raw_input() works in python2 but not python3. Is there a way to do this so that the code is compatible with both python 2 and python 3?

推荐答案

在Python 2中将raw_input绑定到input

Bind raw_input to input in Python 2:

try:
    input = raw_input
except NameError:
    pass

现在input也会在Python 2中返回一个字符串.

Now input will return a string in Python 2 as well.

如果您使用 six 编写2/3兼容代码，则six.input()在Python 2中更改为raw_input()，在Python 3中更改为input().

If you're using six to write 2/3 compatible code then six.input() there points to raw_input() in Python 2 and input() in Python 3.
