如何在Python中将listtrades.txt读取为JSON数组并访问指定字段

• Headings: Use number signs (#). The count of signs matches the heading level — e.g., # Level 1 Heading, ## Level 2 Heading.
• List items: Start each item with a dash (-). For nested lists, indent the sub-items.
• Text emphasis: Wrap text with asterisks (*). Use *italic text* for italics and **bold text** for bold formatting.
• Code/commands: Surround single-line snippets with backticks (`). For multi-line code blocks, use triple backticks (```) and optionally add a language specifier (e.g., ```python).
• Quoted text: Prefix lines with greater than signs (>). For nested quotes, add additional > symbols (e.g., >> Nested quote).
• Links: Wrap the display text in square brackets ([]), followed by the target URL in parentheses (()). Example: [Visit Example Site](https://example.com).
• Images: Use square brackets ([]) for alt text, followed by the image's URL in parentheses (()). Example: [Sunset Over Mountains](https://example.com/sunset.jpg).
