How to get text from dynamically created buttons?

由 一个人想着一个人 提交于 2021-02-15 07:52:05
问题 I want my buttons when i click on them to return the text attribute of them. I've used a for loop to dynamically create the buttons but when i do this the btn variable gets stuck on the last created button meaning every button returns the same text value. listWords = ("Car","Train","Bus","Bike") var = 0 def getdef(): print(btn['text']) for word in listWords: btn = Button(window, text=word,command=getdef) btn.grid(column=var, row=0) var = var + 1 This code produces 4 buttons: Image of buttons

问题 I'm trying to make a memory card matching game in python and I have a folder called 'icons' that has the 21 images that I want to use. I created the buttons in a 6x7 grid using for loops. I put the buttons in a list called buttons which I will later use to keep track of which buttons are still empty and are available for putting images. Using a for loop, I loop over the images in the folder. For each image, I choose a random button from the list which will contain the image. I then remove

Non-standard windows with Tkinter?

由 安稳与你 提交于 2021-02-15 05:02:00
问题 Is there a way to create non-standard windows with Tkinter? I want something of a floating image on the screen, with Tkinter widgets inside. Think something like Growl for Mac, Siri on the iPad, Mac OS volume/brightness change bezels, etc. If this isn't possible, is there a way to get rid of the top bar on the window with the title and close/minimize/resize buttons, and require the script to complete (or modifier-Q keystroke) to close? 回答1: wm_overrideredirect will remove the standard window

用python+opencv写了个程序，在自己电脑上一切正常，但在别人电脑上就是运行不了 报错： Exception in Tkinter callback Traceback (most recent call last): File "tkinter\__init__.py", line 1699, in __call__ File "ShowTheWay.py", line 53, in main NameError: name 'img' is not defined Traceback (most recent call last): File "ShowTheWay.py", line 25, in on_mouse NameError: name 'img' is not defined 然后我又回去查代码，也没有写错啊，后来加了几个检查点，才发现是视频读取这里就已经出了问题 def re_size(): global img img = None re_set() if shipin.isOpened(): ret, frame = shipin.read() h, w, _ = frame.shape img = cv2.resize(frame, (int(w / s), int(h / s)), interpolation= cv2.INTER_AREA)

一.序列应用——猜单词游戏 1. 游戏介绍 猜单词游戏就是计筧机随机产生一个单词，打乱字母顺序，供玩家去猜测。此游戏采用控制字符界面 2. 程序设计思路 游戏中，可使用序列中的元组存储所有待猜测的单词。因为猜单词游戏需要随机产生某个待猜测单词以及随机数字，所以引入random模块随机数函数。其中，random.choice()可以从序列中随机选取元素。 在游戏中，随机挑出一个单词word后，把单词word的字母顺序打乱的方法是随机单词字符串中选择一个位置position，把position位置的字母加入乱序后的单词jumble，同时将原单词word中position位置的那个字母删去（通过连接position位置前字符串和其后字符串实现）。通过多次循环就可以产生乱序后的新单词jumble。 3. 游戏结果展示： 4. 代码： import random WORDS=("python","jumble","easy","difficult","answer","continue","phone","position","game") print( """欢迎参加猜单词游戏 把字母组合成一个正确的单词 """ ) iscontinue="y" while iscontinue=="y" or iscontinue=="Y": #从序列中随机挑出一个单词 word=random
