How to fix this error and What am the issue? edit:now Avast is not blocking .exe(but blocking PIP) 回答1: I use avast as well. Avast sandboxes pipenv when installing a new package. Depending on what/if virtualenv your using.

问题 What would be the best way to give an error and tell the user to only input numbers if they type letters as an input? Code that doesn't work: if self.localid_entry.get() == int(self.localid_entry.get(): self.answer_label['text'] = "Use numbers only for I.D." The variable is obtained in Tkinter with: self.localid2_entry = ttk.Entry(self, width=5) self.localid2_entry.grid(column=3, row=2) 回答1: Something like this: try: i = int(self.localid_entry.get()) except ValueError: #Handle the exception

问题 I have simple example, Entry and three separate Frames. from tkinter import * top = Tk() Entry(top, width="20").pack() Frame(top, width=200, height=200, bg='blue').pack() Frame(top, width=200, height=200, bg='green').pack() Frame(top, width=200, height=200, bg='yellow').pack() # Some extra widgets Label(top, width=20, text='Label text').pack() Button(top, width=20, text='Button text').pack() top.mainloop() Once I start writing in Entry, the keyboard cursor stay there, even when I press with

问题 I'm using Tkinter for a simple trivia game. There are several buttons, one for each answer, and I'd like to run a checkAnswer function with certain parameters when one is clicked. If I used something like the following: self.option1 = Button(frame, text="1842", command=self.checkAnswer(question=3, answer=2)) Then it would run checkAnswer and use what it returned (nothing). Is there a simple way to store the parameters in the button constructor? 回答1: This is exactly what functools.partial() is
