Python3将Unicode String转换为int表示 [英] Python3 convert Unicode String to int representation

问题描述

众所周知，计算机使用数字。我现在正在键入此文本，服务器会从中输入一个数字，当您想要阅读它时，您将从服务器获取文本。

As we all know, a computer works with numbers. I'm typing this text right now, the server makes a number out of it and when you want to read it, you'll get text from the server.

我如何独自完成这项工作？

How can I do this on my own?

我想用我自己的算法加密一些东西，我的算法可以很好地处理整数，但现在我想加密一个字符串，我不知道怎么转换一个Unicode字符串为整数，反之亦然。

I want to encrypt something with my own algorithm and my algorithm works fine with integers, but now I want to encrypt a String and I don't know how to convert a Unicode string to an integer number and vice versa.

我正在使用Python 3.有没有人知道我的问题的优雅解决方案？

I'm using Python 3. Is there anybody who knows an elegant solution for my problem?

推荐答案

您正在寻找 ord（）功能，我认为：

You are looking for the ord() function, I think:

>>> ord('a')
97
>>> ord('\u00c2')
192

要转换一整套字符，请使用列表理解：

To convert a whole set of characters use a list comprehension:

>>> [ord(c) for c in 'Hello World!']
[72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33]

它的反面是 chr（）功能：

It's inverse is the chr() function:

>>> chr(97)
'a'
>>> chr(193)
'Á'
