For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
How can I do an FTP transfer in Python?

"If you think someone's probably done it before, they probably have .... and it's probably available to you" A good answer to many questions of the form "can I do xxxxx in Python?"

Question today "can I do an FTP transfer from Python"

Answer "Yes" [but I had a look around and discovered there was on example on our web site!]

There IS an example now ;-) ... it's [here].

• The ftplib module is distributed with Python, but must be imported into programs in which you wish to use it.
• You create a connection object using the ftplib.FTP method.
• You login with the login method on the connection object.

They you can run a whole series of methods such as pwd and dir to find the current ditectory, and list the current directory.

Methods such as retrbinary can then be used to retrieve files, passing the file retrieval instruction into the FTP connection, and providing a callback which allows the author of the code to output to the screen, to a file, or to process it otherwise.
