使用 ast.literal_eval 或 JSON 解析字典时出错.编写字符串时可能存在错误?蟒

Question

我试图解析从 Python3 中的 Spotify 专辑 API 查询的字典，但收到错误消息：ValueError: malformed node or string使用ast.literal_eval时。使用JSON.loads时，我收到错误消息：SyntaxError: EOL while scanning string literal.

在查看字典时，我看到文本在字符 3072 的 VIM 中不再被识别为字符串，原因我无法弄清楚。这是一个错误，还是我不熟悉的隐藏角色？文本复制在下面和屏幕截图 以显示文本突然从字符串变为常规文本。如何解决此问题以将此文本解析为字典？

Answer 1

在解析之前，您应该将所有单引号替换为双引号。 它是JSON文件的标准

Answer 2

将所有单引号替换为双引号。

True应该是真的，False应该是假的，如果这是有意的，None应该用引号括起来或替换为null。

Answer 3

使用ast 模块，我能够阅读您的字典。

import ast
with open(filename, "r") as infile:    
print(ast.literal_eval(infile.read()))

输出：
