We get the status code in two ways: - extracting the code from the last valid line in the response - getting it from the 3 first digits in the code After a comparison between the two values, we can safely set the code or raise a warning. Examples: - get_status_code_from_code_response('200 Welcome') == 200 - multi_line_code = '226-File successfully transferred 226 0.000 seconds' get_status_code_from_code_response(multi_line_code) == 226 - multi_line_with_code_conflicts = '200-File successfully transferred 226 0.000 seconds' get_status_code_from_code_response(multi_line_with_code_conflicts) == 226 For more detail see RFC 959, page 36, on multi-line responses: https://www.ietf.org/rfc/rfc959.txt "Thus the format for multi-line replies is that the first line will begin with the exact required reply code, followed immediately by a Hyphen, "-" (also known as Minus), followed by text. The last line will begin with the same code, followed immediately by Space , optionally some text, and the Telnet end-of-line code." u iÿÿÿÿiiuZFTP response status code seems to be inconsistent.
