AddRaster using pyqgis

Question

I am able to attach a raster by using python console using the command shown below.

qgis.utils.iface.addRasterLayer('D:/Work/dt0017810q.tif')

But, when the same image/raster path is read from a text file using a customized plugin (which I developed), the addRasterLayer method/function throws an error message

Invalid Layer: GDAL provider Cannot open GDAL dataset D:/Work/dt0017810q.tif : `D:/Work/dt0017810q.tif ' does not exist in the file system, and is not recognized as a supported dataset name. Raster layer Provider is not valid (provider: gdal, URI: D:/Work/dt0017810q.tif

How to fix this?

Answer 1

Just now only I find that while reading a line from a text file, \n will be there at the right end. I checked that value which was read from text file by using 'print' command. In print command, the \n is not displayed a character. Hence I confused.

Now the problem has been solved by using rstrip() function.
