Python - can't upload files on FTP

Question

I'm writing a function to load files into a specific folder of an FTP area, I get an error on "storbinary" line. PS: "Filename" is a global variable

import ftplib from ftplib import FTP

host = "ftp.test.com"
username = "usr"
password = "pwd"

# connect to ftp
ftp = FTP(host=host, user=username, passwd=password)

# set upload directory
ftp.cwd('Test')

# upload file
with open(os.path.join('/root/ftp/output/', Filename), 'w') as fp:
    ftp.storbinary('STOR %s' % os.path.basename(Filename), fp, 1024)

error message: ftp.storbinary('STOR %s' % os.path.basename(Filename), fp, 1024) File "/usr/lib/python3.7/ftplib.py", line 506, in storbinary buf = fp.read(blocksize)

Answer 1

    host = "ftp.test.com"
username = "urs"
password = "pwd"

# FTP connection
ftp = FTP(host=host, user=username, passwd=password)

# change upload directory 
ftp.cwd('test')

# upload file
upload_file = os.path.join('/root/test/ftp/', Filename)
with open(upload_file, 'rb') as fp:
    ftp.storbinary('STOR %s' % os.path.basename(upload_file), fp)
fp.close()

# print the content of directory   
print(ftp.dir())
