# Python Zipfile Module

The `zipfile` module allows you to create, read, write, append, and list a ZIP file.

## Importing the Module

```python
import zipfile
```

## Reading ZIP Files

To read a ZIP file, you can use the `zipfile.ZipFile` class in read mode (`'r'`).

### Listing Files

The `namelist()` method returns a list of archive members by name.

```python
import zipfile

with zipfile.ZipFile('example.zip', 'r') as zip_ref:
    print(zip_ref.namelist())
```

### Extracting Files

*   `extractall()`: Extracts all members from the archive to the current working directory or a specified directory.
*   `extract()`: Extracts a single member.

```python
import zipfile

with zipfile.ZipFile('example.zip', 'r') as zip_ref:
    zip_ref.extractall('extracted_files')
```

## Writing to ZIP Files

To write to a ZIP file, open it in write mode (`'w'`). Note that this will erase the existing file. To append, use append mode (`'a'`).

You can also specify the compression method (e.g., `zipfile.ZIP_DEFLATED`).

```python
import zipfile

with zipfile.ZipFile('new_archive.zip', 'w', zipfile.ZIP_DEFLATED) as zip_ref:
    zip_ref.write('file_to_compress.txt')
```
