使用Python解析指定JSON文件，提取subtasks字段相关内容

Hey there! I’ve put together a straightforward, easy-to-follow breakdown of the Markdown formatting rules you requested, with practical examples to help you apply each one quickly:

Headings #

Use number signs (#) to define heading levels—more # symbols mean smaller, lower-priority headings:

• # Heading Level 1 (largest) → # Heading Level 1
• ## Heading Level 2 → ## Heading Level 2
• ### Heading Level 3 → ### Heading Level 3

List Items #

Start each list entry with a dash (-). For nested lists, just indent the dashes under the parent item:

• Main list item 1
  • Nested sub-item
  • Another nested sub-item
• Main list item 2

Emphasized Text #

Wrap text with asterisks to add emphasis:

• Italics: *This text is italicized* → This text is italicized
• Bold: **This text is bold** → This text is bold

Code & Commands #

Surround inline code or commands with single backticks (`). For multi-line code blocks, use triple backticks (```) and optionally specify the language for syntax highlighting:

• Inline code: npm install react
• Multi-line code block (Python example):

def calculate_sum(a, b):
    return a + b

Quoted Text #

Use greater than signs (>) to create blockquotes. Add extra > for nested quotes:

This is a standard blockquote.

This is a nested quote inside the first one.

Links #

Structure links with square brackets for the display text, followed by the URL in parentheses:
[Stack Overflow](https://stackoverflow.com) → Stack Overflow

Images #

For images, use square brackets for alt text (the text that shows if the image doesn’t load), followed by the image URL in parentheses. You can also add an optional title in quotes:
[Stack Overflow Logo](https://cdn.sstatic.net/Sites/stackoverflow/Img/logo.svg "Official Stack Overflow Logo") → Stack Overflow Logo
