英文:
Convert a string of list to a proper list
问题
The code you provided appears to be attempting to convert a string containing a list of strings into an actual list of strings. The mistake you are making is that the string a contains HTML-encoded double quotes (") instead of regular double quotes ("). You can use the html module to decode the HTML entities and then use ast.literal_eval to parse the list correctly. Here's the corrected code:
import ast
import html
a = """\"[\"123456789\",\"987654321\"]\""""
decoded_a = html.unescape(a)
lst = ast.literal_eval(decoded_a)
This will give you the expected output: ['123456789', '987654321'].
英文:
I have the following:
a = """\"[""123456789"",""987654321""]\""""
I am trying to convert that to a list of strings. I've tried the following:
lst = ast.literal_eval(a)
but this returns all the characters as an individual string. What is the mistake I am doing?
The expected output: ["123456789", "987654321"]

你可以尝试两次使用 literal_eval 来获取一个整数列表，然后将每个整数映射为字符串，如下所示：
from ast import literal_eval as le
lst = le(le(a))
lst = list(map(str, lst))
lst 现在将变成 ['123456789', '987654321']。
英文:
You can try literal_eval twice to get a list of integers and then map each integer to strings like this :
from ast import literal_eval as le
lst = le(le(a))
lst = list(map(str, lst))
lst would now become ['123456789', '987654321']
