Batch Re-projection script syntax error

import arcpy ... sourceWorkspace = "C:\\Users\\tx8p90\\Desktop\\Lesson2" ... targetProjection = "C:\\Users\\tx8p90\\Desktop\\python excercise data\\Lesson1\\contourlines.shp" ... listDataSet = arcpy.ListDatasets(sourceWorkspace) ... try: ... for x in listDataSet: ... outputDataset = sourceWorkspace + "\\projected_" + x ... arcpy.Project_management(x, outputDataset, targetProjection) ... print "Reprojection successful" ... except: ... print arcpy.GetMessages() ... print "failed"

I have started learning Python for ArcGIS last week and have a simple script to reproject all the datasets in a folder. The script says "syntax error- invalid syntax" but I can't find anything. Can someone please have a look? It seems something very basic but I'm pretty new so I don't see it at the moment. Also running this in ArcGIS prints "failed" right away. And the files are in place in the right folders. I have already checked.
