how to read a file on ftp with python?

Question

here is my code:

import ftputil
import urllib2
a_host = ftputil.FTPHost(hostname, username,passw)

for (dirname, subdirs, files) in a_host.walk("/"): # directory
    for f in files:
            if f.endswith('txt'):
                htmlfile = open(f, 'r')
                readfile = htmlfile.read()

I think it should be ok, but I got an error

Traceback (most recent call last):

    htmlfile = open(f, 'r')
IOError: [Errno 2] No such file or directory: u'readme.txt'

where is the problem?

You cannot read the remote file using open like local file. You need to download the file from the remote host first.

for (dirname, subdirs, files) in a_host.walk("/"): # directory
    for f in files:
        if f.endswith('txt'):
            a_host.download(f, f)  # Download first
            with open(f) as txtfile:
                content = txtfile.read()

You need to use a_host.open, not a Python default open.

Thus, instead:

htmlfile = open(f, 'r')
readfile = htmlfile.read()

This:

htmlfile = a_host.open(f, 'r')
readfile = htmlfile.read()
