Hi,
I am getting the error TypeError: seek() takes exactly 2 arguments (3 given),
namely:
$ ./_LogStream.py
Traceback (most recent call last):
File "./_LogStream.py", line 47, in <module>
log_stream.last_line_loc_and_contents()
File "./_LogStream.py", line 20, in last_line_loc_and_contents
self.input_file.seek(-1, 2) # grab the last character
TypeError: seek() takes exactly 2 arguments (3 given)
When I run the below code.
I understand that the extra argument is the "self", but I don't know how to
change my class to make the seek(-1,2) work.
Could you help ?
Thanks,
Ron.
