Issue with code.

Question

class RegisterForm(Form):
    username = StringField(
        'Username', 
        validators=[
            DataRequired(), 
            Regexp(r'^[a-zA-Z0-9_]+$'), 
            message=("Username shourld be one word, letters, numbers, and underscores only."),
            name_exist
        ]
    )
    email = StringField(
        'Email', 
        validators=[
            DataRequired(), 
            Email(), 
            email_exist()
        ]
    )
    password = PasswordField(
        'Password',
        validators=[
            DataRequired(),
            Length(min=5),
            EqualTo('password2', message='Passwords must match')
        ]
    )
    password2 = PasswordField(
        'Confirm Password',
        validators=[DataRequired()]
    )

I get this error message:

SyntaxError: expression cannot contain assignment, perhaps you meant "=="?

The line numbers don't match since this is not the whole code.

Could it be that it should be name_exists (with and "s") and not name_exist?

I agree with Chris. The line:

name_exist

is suspect. My guess/assumption (without testing it) is that it should have the 's' (name_exists) and shouldn't it also be a method/function just like email_exists()? Like this:

name_exists()

I hope that helps. Happy coding!
