Python syntax error with try & except [duplicate]

Question

I'm testing a FTP script in Python 3 to list the files in a directory path give, but when I'm trying with try/except handlers, I'm getting a syntax error.

Below is the script code. Please advise what I'm missing or doing wrong.

#!/usr/bin/python env
import ftplib
def FtpMirroList():
  ftp = ftplib.FTP("ftp.example.com")
  ftp.login("lodgy", "pass123")
  ftp.cwd("/my/research/folder")

  files = []
  try:
    files = ftp.nlst()
  except ftplib.error_perm, resp:
    if str(resp) == "550 No files found":
      printi("No files in this directory")
    else:
      raise
  for f in files:
    printi(f)

FtpMirroList()

It's raising the below error:

  File "./ftplib-example-2.py", line 12
    except ftplib.error_perm, resp:
                            ^
SyntaxError: invalid syntax

Python3 changed the exception syntax but the Python3 syntax can be used in Python2. As pycoder wrote use as instad the comma. If you wanto multiple exceptions to handle then use except (exc1, exc2, exc3) as e:. — Gábor Fekete

#!/usr/bin/python env should be #!/usr/bin/env python

except ftplib.error_perm, resp This synthax is not supported in python3. Replace comma with as.
