Issues with string appending - python

I'm trying to append a string in python and the following code produces

    buildVersion =request.values.get("buildVersion", None)
    pathToSave = 'processedImages/%s/'%buildVersion
    print pathToSave

prints out

   processedImages/V41
   /

I'm expecting the string to be of format: processedImages/V41/

It doesn't seem to be a new line character.

 pathToSave = pathToSave.replace("\n", "")

This dint really help
