问题 I need to rotate a triangle (Not an image) around at the center of the screen. I have seen other people answer this question, but the triangle could not point upwards. I have tried to use other peoples functions, but they see to only work partly, like the function I mentioned above. import pygame disp=pygame.display.set_mode((200,200)) import math def rotate_triange(mouse_pos,triangle_pos): #The code here import time while True: time.sleep(1) pygame.Surface.fill(disp,(255,255,255)) center =

问题 I am using django 2.0 and python 3.6. The user registration includes sending of a verification mail. And this mail sending process is taking longer and the user is kept waiting. What I need?: If the user registration form is valid, mailing details are sent to another task handler and regardless of whether the mail is sent or not, the function must resume and return a response. def new_user_registration(request): form = CustomUserCreationForm(request.POST or None) if form.is_valid(): user =

问题 In my Python3 program that uses the Gmail API, I want to re-instantiate the Gmail "service" instance every few hours for the purpose of enhanced reliability. I am not certain if this is required to better reliability, but I thought it would be useful. So, when I start my program, I run the below function, which as you can see, builds the Gmail "service" instance. Then, after a few hours, I run the same code again. However, this results in socker.timeout errors. I know this because the socket

问题 I apologize if this question has been asked earlier. I am still not clear about encoding in python3.2. I am reading a csv(encoded in UTF-8 w/o BOM) and I have French accents in the csv. Here is the code to opening and reading the csv file: csvfile = open(in_file, 'r', encoding='utf-8') fieldnames = ("id","locale","message") reader = csv.DictReader(csvfile,fieldnames,escapechar="\\") for row in reader: if row['id'] == id and row['locale'] == locale: out = row['message']; I am returning the

问题 I am making a game in pygame. In this game, the background image is large. On the screen, player only sees about 1/20th of the background image. I want, when player presses the left, right, up or down arrow keys, the background image moves respectively, but, it stops moving when player reaches the end of the image. I have no idea how to do this. My code up to this point :- import pygame FPS = 60 screen = pygame.display.set_mode((1000, 1000)) bg = pygame.image.load('map.png') clock = pygame

问题 I would like to compile a python3 package into a distributable binary form (without sourcecode) from within the x64 Native Tools Command Prompt for VS 2019 using python 3.6 (64bit). However, i have problems specifying the correct paths to the files the package should contain. The produced folder structure in the site-packages directory is all wrong and not what i expect from my source folder structure and my setup.py . It seems for me that the modules from the top level package are treated

问题 Tried searching for this and could not find a suitable answer. I know we can do the following to create a menu to the root window in tkinter menu = Menu(root) some_menu = Menu(menu, ....) some_menu.add_command(label = some text, command = some command) .... menu.add_cascade(label = some title, menu = some_menu) root.config(menu = menu) now let's say that we passed some_menu to the root config instead then it would display the cascade menu's options / children horizontally across the top bar
