This is my first attempt to FTP a file from a mainframe. The code:

session = ftplib.FTP('company.lan.com','userid','passwd')
myfile = open('PC.filename','w')
session.retrlines("RETR 'mainframe.filename'", myfile)
myfile.close()
session.quit()
The resulting error is:
Traceback (most recent call last):
File "ftp_from_mf.py", line 5, in <module>
session.retrlines("RETR 'mainframe.filename'", myfile)
File "c:\python26\lib\ftplib.py", line 428, in retrlines
callback(line)
TypeError: 'file' object is not callable
According to the ftplib module documentation:
retrlines(command[, callback])
Retrieve a file or directory listing in ASCII transfer mode. command
should be an appropriate RETR command (see retrbinary()) or a command
such as LIST, NLST or MLSD (usually just the string 'LIST'). The
callback function is called for each line, with the trailing CRLF
stripped. The default callback prints the line to sys.stdout.
IOW callback must be a function. You are passing a file object. I will
guess that you want:
def writer(line):
myfile.write(line + '\n')
session.retrlines("RETR 'mainframe.filename'", writer)
The documentation is in error in that it does not explicitly state that
a line is passed to the callback function as an argument. I am assuming
that is the case.
