Question

I’m looking for a better way to code:

My Code is,

@login_required 
def updateEmInfo(request):        
    userProfile = request.user.get_profile()
    if request.POST.__contains__('userType'):
        userType = request.POST['userType']
    else:
        userType = None

    if request.method == 'POST':
         ~~~~~~~~

If I code as userType = request.POST['userType'], then I get an error if userType is not equal.

I don’t think it is good idea to to use the __contains__ method, is there a better way to write this code?

Something easy like the following

userType = request.POST['userType'] ? request.POST['userType'] : None 

Answer 1

you can use get

request.POST.get('userType')

get(key[, default]) Return the value for key if key is in the
dictionary, else default. If default is not given, it defaults to
None, so that this method never raises a KeyError
