Here is an example code to connect to a FTP server using Python's built-in ftplib module:
```py
import ftplib

# FTP server credentials
FTP_HOST = 'ftp.example.com'
FTP_USER = 'username'
FTP_PASS = 'password'

# Connect to FTP server
ftp = ftplib.FTP(FTP_HOST, FTP_USER, FTP_PASS)

# Get welcome message from FTP server
print(ftp.getwelcome())

# List contents of current directory
ftp.dir()

# Close connection
ftp.quit()
```

You will need to replace FTP_HOST, FTP_USER, and FTP_PASS with the appropriate values for your FTP server. You can then use the ftp object to perform various FTP operations such as uploading and downloading files or navigating directories.
