DJANGO int() argument must be a string, a bytes-like object or a number, not 'list'-CodePudding

Hello sir i have in DJANGO a problem tryin to get my algorithm right please help, much appreciated: MYERROR: int() argument must be a string, a bytes-like object or a number, not 'list'

MYCODE:

def subs(request, pk):
    sw = Swimmers.objects.filter(id=pk).values('sessions')
    sw_list = int(list(sw))
    res = sw_list  1
    print('Data:',sw)
    return JsonResponse(res, safe=False)

CodePudding user response：

You can't convert a list to an int, my suggestion would be:

sw_list = map(int, sw)

This will convert each of the elements of sw to an int

But you're also going to have issues because you can't increment a list either, so on the very next line you'd need something like:

sw_list = map(lambda x: x   1, sw_list)  # instead of sw_list  = 1
