需要将字母更改为其他字母(Python 2.7) [英] Need to change letters to other letters (Python 2.7)

问题描述

我正在做一个学校的小项目，我们基本上需要把已经输入的字母改成另一个字母(从预制列表中选择)，制作一个类似程序的代码机器.我在网上和 stackoverflow 上搜索过，但在上面找不到任何东西，也不知道从哪里开始.

I am making a school mini project, and we basically need to change letters that have been inputted into another letter (which is selected from a premade list), making a code machine like program. I have searched the web and stackoverflow, and cant find anything on it, and dont really know where to start.

我想让程序做的是，假设我输入了你好"这个词.程序会将单词改为loaaw"，例如L为H，A为E，A为L，W为O.收到信件时.

What I want the programme to sort of do is this, say I input the word "hello". The program will change the word to "loaaw" for example, with L being H, A being E, A being L and W being O. These translations will be set before hand, in a big list, basically selecting which letter is sent back when a letter is sent in.

推荐答案

这样的事情?

orig = 'hello'
# table = {'h': 'L', 'e': 'O', 'l': 'A', 'o': 'W' }
# table_tr = dict( (ord(a), ord(b))  for a,b in table.items() ) 
table_tr = str.maketrans('helo', 'LOAW')
res = orig.translate(table_tr)
print(res)

(这是针对python3的；对于python2，你需要import string并使用string.maketrans)

(this is for python3; for python2 you need to import string and use string.maketrans)
