Django python syntax error in views.py -

i had issue web application in django :

syntaxerror @ / invalid syntax (views.py, line 98) request method: request url:    http://craft.irisa.fr/ django version: 1.6.5 exception type: syntaxerror exception value:     invalid syntax (views.py, line 98) exception location: /usr/lib/python3.2/importlib/_bootstrap.py in get_code, line 413 python executable:  /root/craft/trunk/sources/env/bin/python python version: 3.2.3 

a part of code of views.py file :

def login_view(request): """ logs user application """  # redirect if user connected if request.user.is_authenticated():     return httpresponseredirect('/')  if request.method == 'post':     # values sent form     login_form = authenticationform(data=request.post)      # log user in if form valid     if login_form.is_valid():         login(request, login_form.get_user())  #line 98 here :          messages.add_message(request, messages.info, u'welcome '+ request.user.username +'!')          next = request.post.get('next','/')         return httpresponseredirect(next) else:     next = request.get.get('next','/')     # create form     login_form = authenticationform()  # display page return render(request, 'taskhandler/login.html', locals()) 

as can see there no syntax error in line , code works, tested it.

but new thing did : have changed django sgbd sqlite3 postgresql.

those troubles appeared when did these modifications understand why python raises such error ! tried add data in database manage.py shell , had no problem !

thanks !

the problem comes python version,

in python 3.2, 'u' encoding character before string cannot used !
