# Building a JSON Report in Python

## 1\. Understanding the code

The following Python code creates a report using a dictionary, which can later be converted into JSON format.

```python
report = {
    "filename": uploaded_file.name,
    "number_of_pages": page_count,
    "metadata": metadata,
}
```

Please note that this code creates a Python dictionary, not a JSON file by itself. It can be used in a regular Python script or a Streamlit application, provided the required variables have been defined.

## 2\. Breaking down each field

The `report` variable is a Python dictionary that organizes information into key-value pairs. Each key identifies a piece of information, and its corresponding value provides the data associated with it.

In this dictionary, the keys are `"filename"`, `"number_of_pages"`, and `"metadata"`. The corresponding values are `uploaded_file.name`, `page_count`, and `metadata`.

`"filename": uploaded_file.name`

- **Key:** `"filename"`
- **Value:** `uploaded_file.name`, which contains the name of the uploaded file. The `uploaded_file` object must support the `.name` attribute.

`"number_of_pages": page_count`

- **Key:** `"number_of_pages"`
- **Value:** `page_count`, which contains the total number of pages in the document.

"metadata": metadata

- **Key:** `"metadata"`
- **Value:** `metadata`, which contains additional document information, such as the author, title, or creation date.

The variables `uploaded_file`, `page_count`, and `metadata` must be defined before creating the report.

**Example output:**

The dictionary could contain the following information:

```python
{
    "filename": "sample.pdf",
    "number_of_pages": 5,
    "metadata": {
        "title": "Sample Document",
        "author": "John Doe"
    }
}
```

The values shown above are examples. Your actual output depends on the uploaded file and the metadata you extract.
