"FTP client in Python using ftplib"

FTP (File Transfer Protocol) is a standard network protocol used to transfer files between computers on a TCP-based network, such as the internet. Here's an example of a basic implementation of an FTP client in Python using the ftplib library:

This code defines a function ftp_client which takes the host, user and password of the server as input, creates an FTP object and connects to the specified host using the login credentials. Once the connection is established, it changes the working directory to root directory by calling ftp.cwd('/') method and prints the list of files and directories in the current working directory by calling ftp.retrlines('LIST') method. Finally it closes the connection by calling ftp.quit() method.

This is just a basic example of how to use Python and the ftplib library to create a simple FTP client. In a real-world scenario, you would need to add more functionality such as uploading and downloading files, error handling, and handling different file types.

To run this code, you will need to have Python development environment installed and the ftplib library. You can use IDLE (which is included with the Python installation), PyCharm Community Edition, and Visual Studio Code with the Python extension.

Additionally, you may also explore other libraries such as pyftpdlib and asyncftp for more advanced FTP functionality.
