How to download a file on FTP by using Python

Question

I'm trying to download a couple of files (csv, pdf, ..) on a FTP server by using a Python library called urllib.request.

I made this code who unfortunately doesn't word since I'm getting an error.

CODE :

import urllib.request

urllib.request.urlretrieve('ftp://user_name:password@host_name:port_number/users/appli/gedftp/data/BO/LME/TEST_CSV_INTE.csv', 'file')

ERROR :

URLError: <urlopen error ftp error: error_perm('550 users/appli/gedftp/data/BO/LME: No such file or directory.')>

Yet, in FileZilla, I can see that the directory/file exists.

Here is .xml configuration of the FTP server in FileZilla (I didn't put the real info) :

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<FileZilla3>
    <Servers>        
        <Server>
            <Host>host_name</Host>
            <Port>port_number</Port>
            <Protocol>0</Protocol>
            <Type>0</Type>
            <User>gedftp</User>
            <Pass>password</Pass>
            <Account>test</Account>
            <Logontype>4</Logontype>
            <TimezoneOffset>0</TimezoneOffset>
            <PasvMode>MODE_DEFAULT</PasvMode>
            <MaximumMultipleConnections>0</MaximumMultipleConnections>
            <EncodingType>Auto</EncodingType>
            <BypassProxy>0</BypassProxy>
            <Name>server_name</Name>
            <Comments />
            <LocalDir />
            <RemoteDir />
            <SyncBrowsing>0</SyncBrowsing>server_name&#x0A;        
        </Server>
            </Servers>
</FileZilla3>

EDIT :

I get the same problem with ftplib :

import ftplib

FTP_HOST = "host_name"
FTP_USER = "gedftp"
FTP_PASS = "password"

ftp = ftplib.FTP(FTP_HOST, FTP_USER, FTP_PASS)
ftp.encoding = "utf-8"

filename = "/users/appli/gedftp/data/BO/LME/TEST_CSV_INTE.csv"
 
with open(filename, "rb") as file:
    # Command for Uploading the file "STOR filename"
    ftp.storbinary(f"STOR {filename}", file)

FileNotFoundError: [Errno 2] No such file or directory: '/users/appli/gedftp/data/BO/LME/TEST_CSV_INTE.csv'

Do you have any idea how to fix this or any other proposition ?

Answer 1

As answered in the comment, it seems that you have used the file path /users/appli/gedftp/data/BO/LME/TEST_CSV_INTE.csv in your local code and trying to open it on your local machine, while you were actually referencing a file which is located on server.

That's why opening the file locally failed :)
