Why do I require an "elif" statement here?

Could somebody tell me why I need the "elif char == '\n'" in the following code? This is required in order the pick up lines with just spaces in them. Why doesn't the "else:" statement pick this up? OLD_INDENT = 5 # spaces NEW_INDENT = 4 # spaces print 'Reindent.py:' print '\nFrom file %s' % in

Re: Why do I require an "elif" statement here?

Jim, what you wrote should work correctly. I'm curious as to why you are doing it this way though. An easier way would be to take out all this character processing and use the builtin string processing. See this code: --- whitespace = " " old_indent = 3 new_indent = 5
