[Tutor] Passing command line argument in function

[Gary Taylor]

I'm trying to pass the name of a file as the first argument
to the ftp.storbinary function(?) below.  The only thing I
can get to work is the real file name hard coded as the
argument.  I've tried parenthesis, single quotes, double
quotes, and many combinations of the previous. I've tried
passing sys.argv[1] directly as well, although with fewer
experiments.
 
I invoke this as below and the output is what I would
expect, but the file name on the ftp server is never
correct.


What is the correct way to do this? 


$ ./garyftp.py align.ps
align.ps

Python 2.3.4 on Linux.

#!/usr/bin/python
import sys
from ftplib import FTP

file_to_transfer = sys.argv[1]

ftp = FTP()
ftp.connect("myserver")
ftp.login("myusername", "mypasswd")


ftp.storbinary(stor file_to_transfer, open(file_to_transfer,"r"))

print file_to_transfer
ftp.quit()
