[Tutor] TypeError: 'str' object is not callable

Here is my script:

Here is the error:

The above script was created using the following script:

send_file.r1.py

#
# This script obtains a directory listing, strips the extensions and telnets
to the
# device (which is the filename in the directory). Then it writes the
commands in the
# file to the device, saves config and writes it back to SYSMAN. It can be
run using:
#    python send_file.py
#
# Note: "os" is imported for future functionality.
#
# by: TCDH
# on: 10/17/05
# revised: 10/18/05    TCDH - Added logic to check for offline devices and
sign-on failures.

They both use the same syntax to open the input file, however only
send_file.py receives an error. What gives?
