私の python2 スクリプトは、この方法を使用してファイルを適切にアップロードしますが、python3 は問題を提示しており、次にどこに行くべきかについて行き詰まっています (グーグルは役に立ちませんでした)。

from ftplib import FTP
ftp = FTP(ftp_host, ftp_user, ftp_pass)
ftp.storbinary('STOR myfile.txt', open('myfile.txt'))

私が得るエラーは

Traceback (most recent call last):
  File "/Library/WebServer/CGI-Executables/rob3/functions/cli_f.py", line 12, in upload
    ftp.storlines('STOR myfile.txt', open('myfile.txt'))
  File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/ftplib.py", line 454, in storbinary
    conn.sendall(buf)
TypeError: must be bytes or buffer, not str

コードを次のように変更してみました

from ftplib import FTP
ftp = FTP(ftp_host, ftp_user, ftp_pass)
ftp.storbinary('STOR myfile.txt'.encode('utf-8'), open('myfile.txt'))

しかし、代わりにこれを手に入れました

Traceback (most recent call last):
  File "/Library/WebServer/CGI-Executables/rob3/functions/cli_f.py", line 12, in upload
    ftp.storbinary('STOR myfile.txt'.encode('utf-8'), open('myfile.txt'))
  File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/ftplib.py", line 450, in storbinary
    conn = self.transfercmd(cmd)
  File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/ftplib.py", line 358, in transfercmd
    return self.ntransfercmd(cmd, rest)[0]
  File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/ftplib.py", line 329, in ntransfercmd
    resp = self.sendcmd(cmd)
  File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/ftplib.py", line 244, in sendcmd
    self.putcmd(cmd)
  File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/ftplib.py", line 179, in putcmd
    self.putline(line)
  File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/ftplib.py", line 172, in putline
    line = line + CRLF
TypeError: can't concat bytes to str

誰でも私を正しい方向に向けることができますか

The issue is not with the command argument, but with the the file object. Since you're storing binary you need to open file with 'rb' flag:

>>> ftp.storbinary('STOR myfile.txt', open('myfile.txt', 'rb'))
'226 File receive OK.'
