Tkinter 6 – Labels in tkinter<\/h2>\n

A little example about making a little app with tkinter<\/strong> to make a multiple choice interactive quiz with just labels and the bind method. Just some lines of code with a couple of classes<\/strong> and a function<\/strong> to make a nice test. You can start from this code to make a more complex test that your students could make or to learn something about tkinter<\/strong>.<\/p>\n

The video: live coding to make a quiz with python and tkinter<\/h2>\n

The following video was made “live” and it lasts 14 minutes. You will see how it is possible to make a quiz with tkinter and just labels. Not a very complicated stuff, but it works and it shows something like classes to make labels in a fastest way for the purpose of the app.<\/p>\n

import tkinter as tk\r\n\r\nroot = tk.Tk()\r\n\r\n\r\ndef check(answer):\r\n    if answer[-1] == \"*\":\r\n        print(\"Right, it is {}\".format(answer[:-1]))\r\n    else:\r\n        print(\"Wrong\")\r\n\r\n\r\nclass Question:\r\n    def __init__(self, question):\r\n        self.question = question\r\n        self.label = tk.Label(root, text=question)\r\n        self.label.pack()\r\n\r\n\r\nclass Answer:\r\n    def __init__(self, answer):\r\n        self.answer = answer\r\n        self.label = tk.Label(root, text=answer[:-1])\r\n        self.label.bind(\"<Button-1>\", lambda x: check(answer))\r\n        self.label.pack()\r\n\r\n# Put here the question and answers separated by comma\r\n# right answer ends with *, wrong one ends with -\r\n\r\n\r\nq = \"\"\"What is the capital of Italy?, Rome*, Paris-, London-,\r\nWhat is the capital of France?, Rome-, Paris*, London-\r\n\"\"\"\r\n\r\nq = q.splitlines()\r\nq2 = []\r\nfor line in q:\r\n    q2.append(line.split(\",\"))\r\nq = q2\r\n\r\nfor quest in q:\r\n    Question(quest[0])\r\n    for ans in quest[1:]:\r\n        Answer(ans)\r\n\r\n\r\nroot.mainloop()\r\n<\/pre>\n
