SyntaxError：使用 flask_wtf package 时语法无效

Question

I tried to use the flask_wtf in my python2 script but i get this error

    File "bartender.py", line 16, in <module>
    from flask_wtf import FlaskForm
  File "/usr/local/lib/python2.7/dist-packages/flask_wtf/__init__.py", line 1, in <module>
    from .csrf import CSRFProtect, CsrfProtect
  File "/usr/local/lib/python2.7/dist-packages/flask_wtf/csrf.py", line 220
    dest = f'{view.__module__}.{view.__name__}'
                                              ^
SyntaxError: invalid syntax

here is my import line

from flask import Flask, render_template, jsonify, request, redirect, url_for
from multiprocessing import Process
from flask_wtf import FlaskForm
from wtforms import StringField, IntegerField
from wtforms.validators import NumberRange, Length

I know python3 is out and we should use this but this is a very ols script from me and i tried to extend it and I also do a python3 portation:)
