As several folks have noted  requests doesn t support FTP but Python has other libraries that do  If you want to keep using the requests library  there is a requests-ftp package that adds FTP capability to requests  I ve used this library a little and it does work  The docs are full of warnings about code quality though  As of 0 2 0 the docs say  This library was cowboyed together in about 4 hours of total work  has no tests  and relies on a few ugly hacks    import requests  requests ftp requests ftp monkeypatch session   response   requests get  ftp   example com foo txt
