Importing tkinter in Flask

Question

I'm new to PythonAnywhere, and when I try to import tkinter using Flask putting from tkinter import * after the line from flask import Flask , it shows an error saying: " 'from tkinter import *' used; unable to detect undefined names ".

How do I have to import tkinter, then?

Answer 1

Your code editor is automatically running a linter like flake8 or pyflakes , and it is this linter that tells you that it cannot detect common coding errors because you are using a from <modulename> import * statement. That's because a linter cannot know up front what names that statement will import.

In other words, this is not a Python error . Nor is it specific to PythonAnywhere.

You can avoid the message by importing only what you are actually using in your code:

from tkinter import Frame, StringVar, Label
