I've began accepting user input :( in an old program. The input comes
from a simple text file where users enter filenames (one per line). What
is the appropriate way to handle blank lines that hold whitespace, but
not characters? Currently, I'm doing this:
for user_file in user_files:
# Remove whitespace and make lowercase.
file_skip_list.append(user_file.strip().lower())
file_skip_list = list(sets.Set(file_skip_list))
However, if the input file has blank lines in it, I get this in my list:
'' (that's two single quotes with noting in between)
I thought I could do something like this:
if user_file == None:
pass
Or this:
if user_file == '':
pass
But, these don't work, the '' is still there. Any suggestions are
appreciated!
