使用divmod()出现错误

谢谢楼主，我也知道数据类型错误，但不知道错在哪里，求帮我看一下。
class Pagination(object):
    def __init__(self,request,queryset,page_param="page",page_size=10,plus=5):
        page=request.GET.get(page_param,'1')
        if page.isdecimal():
            page=int(page)
        else:
            page=1
        self.page=page
        self.page_size=page_size
        self.start = (page - 1) * page_size
        self.end = page * page_size
        self.page_queryset=queryset[self.start:self.end]
        total_count=queryset.count
        total_page_count, div = divmod(total_count, page_size)
        if div:
            total_page_count += 1
        self.total_page_count=total_page_count
        self.plus=plus
