You will need a SFTP client to read the files. You cant directly replace the path with hostname. You should try something like paramiko for file ready.
A quick sample:
client= ssh_client.open_sftp()
file = sftp_client.open('your_filename')
try:
for line in file:
#Do whatever you want for each line in the file
finally:
file.close()
