# Using Python with SFTP

Uploading and downloading files with Python is a great way to automate transfers or build out support for SFTP inside you application.

## How to use SFTP with Python

Using Python with SFTP (SSH File Transfer Protocol) can be accomplished using the `paramiko` library, which allows you to create SSH connections and perform file operations securely. Here's a basic guide on how to use Python with SFTP using `paramiko`:

1. **Install Paramiko**: Before you can use Paramiko, you need to install it. You can install it via pip:

   ```bash
   pip install paramiko
   ```
2. **Connect to the SFTP Server**: Below is an example of how to connect to an SFTP server using Paramiko:

   ```python
   import paramiko

   # Define SFTP connection parameters
   hostname = 'sftp.example.com'
   port = 22
   username = 'your_username'
   password = 'your_password'

   # Create an SSH client
   ssh_client = paramiko.SSHClient()
   ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

   # Connect to the SFTP server
   ssh_client.connect(hostname, port, username, password)

   # Create an SFTP session
   sftp = ssh_client.open_sftp()

   # Now you can perform SFTP operations
   ```
3. **Perform SFTP Operations**: Once you've established an SFTP connection, you can perform various operations such as uploading files, downloading files, listing directory contents, creating directories, etc. Here are a few examples:
   * **Upload a file**:

     ```python
     local_file = '/path/to/local/file.txt'
     remote_file = '/path/to/remote/file.txt'
     sftp.put(local_file, remote_file)
     ```
   * **Download a file**:

     ```python
     remote_file = '/path/to/remote/file.txt'
     local_file = '/path/to/local/file.txt'
     sftp.get(remote_file, local_file)
     ```
   * **List directory contents**:

     ```python
     directory = '/path/to/directory'
     files = sftp.listdir(directory)
     ```
   * **Create a directory**:

     ```python
     new_directory = '/path/to/new/directory'
     sftp.mkdir(new_directory)
     ```
4. **Close the Connection**: After you've finished with the SFTP operations, make sure to close the connection:

   ```python
   sftp.close()
   ssh_client.close()
   ```

By following these steps, you can use Python to interact with SFTP servers securely and perform various file operations. Make sure to handle exceptions and errors appropriately, especially when dealing with network connections and file operations.

## Using Paramiko and Python with Couchdrop

Couchdrop has full support for SFTP uploads with python using Paramiko. Simply use your Couchdrop hostname and credentials and you can connect to Couchdrop like any other SFTP server. 

Couchdrop also has a comprehensive API, that you can find [couchdrop-api](https://app.gitbook.com/o/-LkbgP0oCm11Q2blOdYc/s/-LkbgRCdjHoj3ox1LDZc/ "mention")
