I of the main features of an FTP server is the ability to store and recollect files. In this tutorial, you volition learn how you can download and upload files on an FTP server using Python.

We volition exist using Python's built-in ftplib module, we gonna use a exam FTP server for this tutorial, it is called DLPTEST, let'south define its information:

          import ftplib  FTP_HOST = "ftp.dlptest.com" FTP_USER = "[email protected]" FTP_PASS = "SzMf7rTE4pCrf9dV286GuNe4N"        

The password can modify from time to time, make sure you lot visit their website for the right credentials, connecting to this server:

          # connect to the FTP server ftp = ftplib.FTP(FTP_HOST, FTP_USER, FTP_PASS) # strength UTF-8 encoding ftp.encoding = "utf-viii"        

Uploading Files

To upload a file, we gonna need to employ the ftp.storbinary() method, the beneath lawmaking handles that:

          # local file name you desire to upload filename = "some_file.txt" with open(filename, "rb") as file:     # apply FTP's STOR command to upload the file     ftp.storbinary(f"STOR {filename}", file)        

Nosotros opened the file with the "rb" mode, which ways we're reading the local file in binary style.

After that, we used the FTP'due south STOR control, which stores the file in binary style, information technology transfers that file to a new port. Notation that the file must exist in your local working directory, otherwise this won't piece of work.

This exam server will delete the file subsequently xxx minutes, t o make sure the file is successfully uploaded, we need to listing all files and directories using the ftp.dir() method:

          # list electric current files & directories ftp.dir()        

Sure plenty, the file is there:

          drwxr-xr-x    2 dlptest9   dlptest9        40960 Apr 11 07:04 . drwxr-xr-10    two dlptest9   dlptest9        40960 Apr 11 07:04 .. -rw-r--r--    1 dlptest9   dlptest9          172 April 11 07:00 357299070163503-2020-04-11-11-59.txt -rw-r--r--    1 dlptest9   dlptest9          171 Apr eleven 07:01 357299070163503-2020-04-eleven-12-00.txt -rw-r--r--    1 dlptest9   dlptest9          171 Apr 11 07:02 357299070163503-2020-04-eleven-12-01.txt -rw-r--r--    i dlptest9   dlptest9          171 Apr 11 07:03 357299070163503-2020-04-11-12-02.txt -rw-r--r--    i dlptest9   dlptest9           20 Apr xi 07:04 some_file.txt -rw-r--r--    1 dlptest9   dlptest9           24 Apr 11 07:00 syslogtest_be.txt        

Downloading files

At present let's endeavour to download that same file again:

          # the name of file y'all want to download from the FTP server filename = "some_file.txt" with open(filename, "wb") as file:     # use FTP'southward RETR command to download the file     ftp.retrbinary(f"RETR {filename}", file.write)        

This fourth dimension, we're opening the local file in "wb" style, every bit nosotros're gonna write the file from the server to the local car.

Nosotros're using RETR control, which downloads a copy of a file on the server, we provide the file name nosotros desire to download as the showtime argument to the command, and the server will send a copy of the file to us.

The ftp.retrbinary() method takes the method to call when storing the file on the local car every bit a second statement.

If you lot have deleted that file and run the above code, you'll see the file will appear once again, we've successfully downloaded the file!

Finally, y'all got to quit and close the FTP connection:

          # quit and close the connectedness ftp.quit()        

Alright, we are washed with the tutorial, I have separated the code of downloading and uploading scripts, check them here.

Finally, if yous're a beginner and desire to acquire Python, I suggest you havePrincipal Python in five Online Courses from the University of Michigan, in which you'll larn a lot about Python, good luck!
