Read FTP file contents in Python and use it at the same time for Pandas and directly

Question

I am trying to download a file from an FTP server in memory, transform it to a dataframe but also return it as bytes. Code as follows:

import io
import panda         


        

Answer 1

read_csv probably closes the "file". So read it before you call read_csv:

download_file.seek(0)
contents = download_file.read()
download_file.seek(0)
file_to_process = pd.read_csv(download_file, engine='python')

Answer 2

I think that's easier with tentaclio package :

with tentaclio.open("ftp://user:password@host/path/name_file.csv") as reader:
    df = pd.read_csv(reader)
