>>> print "F:\Fire_scar_mapping\ILS3\ndvi_test","TIFF"
F:\Fire_scar_mapping\ILS3
dvi_test TIFF

Notice anything wrong with that? Unlike the Windows command line,
Python neither knows nor cares that the string you're entering is a
file name. It sees the \n and converts it to a newline. Either double
up your backslashes ( "F:\\Fire_scar_mapping\\ILS3\\ndvi_test"), use a
raw string (r"F:\Fire_scar_mapping\ILS3\ndvi_test") or use forward
slashes ("F:/Fire_scar_mapping/ILS3/ndvi_test")
