python - 我有一个字典 Python 2.7 的错误

Question

我制作的词典将字母替换为短划线 (-) 和两个数字。在我的字典里，“t”=“-21”。当我从字典中调用“t”时，我得到“-21”。但是当我调用 replace_all(text, dic) 时，输出是“-2--5-63-5-63”知道出了什么问题吗？

快速编辑:

这是为了让文本不可读，通过一遍又一遍地改变它。在不破坏我的程序的情况下，我不能将我的字符串变成它自己的字典。这是为了一次更改整个段落中的字符。

此外，“replace_all(text, dic)”的代码是我在网上找到的，我不确定它是如何工作的。

这是我的程序:

from Tkinter import *
import time

def replace_all(text, dic):
    for i, j in dic.iteritems():
        text = text.replace(i, j)
    return text

Answer 1

“t”替换为“-21”

然后“1”被替换为“-55”

然后两个“5”都被“-59”替换，结果是“-2--59-59”

然后将两个“9”都替换为“-63”，得到返回的“-2--5-63-5-63”。

如果您不想替换之前替换的字母之一，请考虑一次替换一个字母:

def replace_all(text, dic):
    return ''.join(dic.get(x, x) for x in text)

get 中的第二个 x 是默认值，以防 dict 没有键 x .
