input()和文字unicode解析 [英] input() and literal unicode parsing

问题描述

使用 input()将反斜杠用作文字反斜杠，因此我无法使用unicode解析字符串输入.

Using input() takes a backslash as a literal backslash so I am unable to parse a string input with unicode.

我的意思是

将类似"\ uXXXX \ uXXXX \ uXXXX" 的字符串粘贴到 input()调用中，将被解释为"\\ uXXXX \\ uXXXX \\ uXXXX" ，但我希望它以单个字符而不是两个单独的字符的形式读取 \ u .

Pasting a string like "\uXXXX\uXXXX\uXXXX" into an input() call will become interpreted as "\\uXXXX\\uXXXX\\uXXXX" but I want it read \u as a single character instead of two separate characters.

有人知道如何或可能实现它吗?

Does anyone know how or if possible to make it happen?

我正在接受上述输入并将其转换为如下的ascii.

I am taking input as above and converting it to ascii such as below..

import unicodedata

def Reveal(unicodeSol):
    solution = unicodedata.normalize('NFKD', unicodeSol).encode('ascii', 'ignore')
    print(solution)

while(True):
    UserInput = input("Paste Now: ")
    Reveal(UserInput)

根据我标记的答案，正确的解决方案是:

Per the answer I marked, a correct solution would be:

import unicodedata
import ast

def Reveal(unicodeSol):
    solution = unicodedata.normalize('NFKD', unicodeSol).encode('ascii', 'ignore')
    print(solution)

while(True):
    UserInput = ast.literal_eval('"{}"'.format(input("Paste Now: ")))
    Reveal(UserInput)

推荐答案

如果可以确定输入中不包含引号，则可以通过在两端加上引号将输入转换为字符串文字表示形式，然后使用 ast.literal_eval()将其评估为字符串.示例-

If you can be sure that input would not contain quotes, you can convert the input into a string literal representation, by adding quotes in both ends , and then use ast.literal_eval() to evaluate it into a string. Example -

import ast
inp = input("Input : ")
res = ast.literal_eval('"{}"'.format(inp))

如果输入中可以包含引号，则可以在使用ast.literal_eval进行评估之前，将双引号替换为 r'\'.

If the input can contain quotes you can replace double quotes with r'\"' before evaluating using ast.literal_eval .
