flask项目运行报错SyntaxError: invalid syntax

[lhkagxy]

小弟自学flask，自己写了几行代码，运行时总是报错SyntaxError: invalid syntax，经过测试锁定了有问题的代码，但是找不到原因，求大神指点。
代码如下：
class CreateUserForm(Form):
email = StringField('电子邮箱：', validators=[Required(), Length(1, 64),Email()])
password = PasswordField('密码：', validators=[
Required(), EqualTo('password2', message='两次输入的密码不一致！')])
password2 = PasswordField('再次输入密码：', validators=[Required()])
name = StringField('姓名：', validators=[Required()]

role = SelectField('权限：', coerce=int)
department=SelectField('部门：', coerce=int)
submit = SubmitField('创建用户')

def __init__(self, user, *args, **kwargs):
super(CreateUserForm, self).__init__(*args, **kwargs)
self.role.choices = [(role.id, role.name)
for role in Role.query.order_by(Role.name).all()]
self.department.choices = [(department.id, department.name)
for department in NextDepartment.query.order_by(NextDepartment.name).all()]
self.user = user

def validate_email(self, field): #email字段验证函数
if User.query.filter_by(email=field.data).first():
raise ValidationError('该邮箱已经注册用户！')

报错信息如下：
Traceback (most recent call last):
File "manage.py", line 9, in <module>
File "E:\easy_erp\app\__init__.py", line 38, in create_app
File "E:\easy_erp\app\main\__init__.py", line 7, in <module>
File "E:\easy_erp\app\main\views.py", line 10, in <module>
from .forms import CreateUserForm
File "E:\easy_erp\app\main\forms.py", line 18
role = SelectField('姓名：', coerce=int)
^
SyntaxError: invalid syntax

求大神指点。谢谢！
