Answer 1

Problem in comas after fields in you models, just remove it.模型中的字段后出现昏迷问题，只需将其删除即可。

all code like a = 1, python means as a = (1,)所有代码如a = 1, python 表示为a = (1,)

Answer 2

just remove the (,) from forms.py file there is no need to give , between two fields只需从 forms.py 文件中删除 (,) 就无需在两个字段之间给出 ,

forms.py表格.py

class Page1(forms.Form):
    user_sir_name = forms.CharField(
        label='姓',
        max_length=20,
        required=True,
        widget=forms.TextInput(),
    )
    user_given_name = forms.CharField(
        label='名',
        max_length=20,
        required=True,
        widget=forms.TextInput(),
    )
    user_sex = forms.ChoiceField(
        label='性別',
        widget=forms.Select,
        choices=EMPTY_CHOICES + GENDER_CHOICES,
        required=True,
    )
