![]() Then we create the name of the file we want to save to and open it in write-binary mode. ftp.retrbinary('RETR ' + 'README.html', f.write)įor this example, we login to the Debian Linux FTP and change to the debian folder. Let’s find out how to download a single file: You will almost always want to download a file from the server. Just viewing what’s on an FTP server isn’t all that useful. You could also use your ftp object’s dir function to get a listing of the current folder. ![]() Then we used the cwd command to change our working directory to a different folder and then re-ran the LIST command to see what was in it. In this example, we called LIST which retrieves a list of files and/or folders along with their respective informations and prints them out. The retrlines method prints out the result of the command we called. This is done by calling our ftp object’s retrlines method. Here we get logged in and then we send the LIST command to the FTP server. Let’s learn how to see what’s on the FTP server and change directories! Here is some code that demonstrates the normal method of doing so:ĭrwxr-xr-x 26 0 11 4096 Apr 29 20:31 users If you want to secure your connection, then you will need to call prot_p to do so. The FTP_TLS class supports a keyfile and a certfile. If the FTP server that you’re connecting to requires TLS security, then you will want to import the FTP_TLS class instead of the FTP class. ![]() However, the idea is to convey how to connect to a port that differs from the default. This code will fail as the FTP server in this example doesn’t have port 12345 open for us. If you happen to need to connect to the FTP server using a non-standard port, then you can do so using the connect method. Since we did not pass a username or password, Python assumes we want to login anonymously. Then we create an instance of the class by passing it the host that we want to connect to. Here we import the **FTP** class from ftplib. '230 Guest login ok, access restrictions apply.' Open up the Python interpreter in your terminal or use IDLE to follow along: The official Python documentation uses, so feel free to try that as well. They aren’t just FTP though, so be sure that you choose the correct protocol or you will receive a connection error.įor this example, we will use. ![]() If you go to Fedora’s website ( ) you will find a long list of mirrors that you can use. For example, most Linux distributions have FTP mirrors that are publicly accessible. The first thing we need to do is find an FTP server to connect to. Instead we will focus on the following topics: However the full specification is outside the scope of this article. You can learn all about the File Transfer Protocol by reading the RFC 959 document on the Internet. Python provides an File Transfer Protocol module in its standard library called ftplib that implements the client side of the FTP protocol. The File Transfer Protocol (FTP) is used by many companies and organizations for sharing data. ![]()
