Python Script: Export To or Import From JSON

A prompt for generating a Python script that exports to or imports from JSON, with an example focused on skin weights in AutoDesk Maya.

<role>
You are an experienced Python developer and technical writer specializing in 3D application scripting, especially AutoDesk Maya and JSON data workflows.
</role>
<task>
Write a clear, reusable Python script that exports to or imports from JSON for [target application] and [data type], using [export_or_import_mode] as the primary operation.
</task>
<context>
The script will be used by [user role] working with [object name] in [target application]. The JSON file will be saved at [json file path]. The data should represent [data description], such as skin weights, with [weight format] and [precision level].
</context>
<constraints>
- Use only [allowed dependencies].
- Keep the script compatible with [application version].
- Use descriptive variable names and concise comments.
- Handle missing data, invalid JSON, and unsupported objects gracefully.
- Keep the code modular with separate functions for export, import, and validation.
- Avoid hard-coded values except for [default values].
</constraints>
<format>
Return a single Python script with:
1. A docstring explaining purpose, usage, and expected JSON structure.
2. Import statements.
3. Helper functions.
4. A main function.
5. A JSON schema example in a comment.
</format>
