Pythonwin: Red squiggley underline and syntax error

[Brent W. Hughes]

I copied and pasted some text into my Python code and then Pythowin put a 
red squiggley underline under the two tabs at the beginning of the line. 
What does that mean?  I've tried various things including deleting the white 
space in front of the line and reinserting the tabs.  I've also tried 
retyping the entire line.  Sometimes, I can get the red line to go away but 
when I try to run the program, it gives me a syntax error on the line that 
had the red underline.  Help!
