ast.literal_eval无效（要列出的列表的python字符串）

I am trying to convert the following string of a list back to a list.

我试图将列表的以下字符串转换回列表。

[('zX7XjZ1Vwai5UbqNDDJ1NQ', 570512, [155])]

I have tried both eval() and ast.literal_eval but for some reason when I print the type of my converted string it is still a string (but with the quotations removed)

我已经尝试了eval()和ast.literal_eval,但出于某种原因,当我打印转换后的字符串的类型时,它仍然是一个字符串(但删除了引号)

I have also tried using json.loads()

我也尝试过使用json.loads()

It seems like no matter how hard I try, I cannot convert this string of a list to a python list!

似乎无论我怎么努力,我都无法将这个列表的字符串转换为python列表!

You probably have an additional set of quotation marks, not shown in the question, included in the literal you're evaluating:

您可能还有一组额外的引号,未在问题中显示,包含在您正在评估的文字中:

[('zX7XjZ1Vwai5UbqNDDJ1NQ', 570512, [155])]

is a list, whereas:

是一个列表,而:

"[('zX7XjZ1Vwai5UbqNDDJ1NQ', 570512, [155])]"

is a string.

是一个字符串。

Therefore,

ast.literal_eval("[('zX7XjZ1Vwai5UbqNDDJ1NQ', 570512, [155])]")

returns a list, whereas:

返回一个列表,而:

ast.literal_eval('''"[('zX7XjZ1Vwai5UbqNDDJ1NQ', 570512, [155])]"''')

returns a string. The nested quotes have become verbose in these examples written as Python source code, but perhaps you've read "[('zX7XjZ1Vwai5UbqNDDJ1NQ', 570512, [155])]" from a file.

返回一个字符串。在这些以Python源代码编写的示例中,嵌套引号已经变得冗长,但是您可能已经从文件中读取了“[('zX7XjZ1Vwai5UbqNDDJ1NQ',570512,[155])]”。
