问题 So I am creating a memoized class, and have been observing a strange behavior. Here's the snippet of the code: class SomeClass(object): _Memoized = {} def __new__(cls, id: str, *args, **kwargs): if id not in cls._Memoized: print('New Instance') cls._Memoized[id] = super(SomeClass, cls).__new__(cls, *args, **kwargs) else: print('Existing Instance') return cls._Memoized[id] def __init__(self, id: str): print('Running init') self.id = id def test(): w1 = SomeClass(id='w1') wx = SomeClass(id='w1'

问题 Below is my script which calls another script using below example and produces entire output after execution is completed while expectation is that it should produce live output as well as write in file at the same time.

Python Tkinter small window pops up momentarily before main window

问题 Hello I am making a Python Tkinter GUI program but as I was making it I noticed that a small Tkinter window pops up then closes before the main window pops up. It is very distracting and obviously something that you would have in a professional piece of software. Here is an example of the problem: from tkinter import * app = Tk() app.title("My GUI") app.iconbitmap(r"C:\Program Files (x86)\Notepad++\Files\journalicon.ico") app.resizable(0,0) button = Button(text = "Text") button.pack() app

Does __await__ need to be a generator?

折月煮酒 提交于 2019-12-24 09:50:10

Objects with __await__ method are called Future-like objects in the rest of this PEP. It is a TypeError if __await__ returns anything but an iterator. In my experience, before await was a statement, yield from was used together with coroutines implemented as generators. Nowadays python (I'm using 3.5) has asynchronous methods using

No image pop-up or display for plt.imshow() and plt.show()

风格不统一 提交于 2019-12-24 08:37:14
问题 I was trying to recreate the cocoapi demo script by copy pasting it into my own local script instead of running it on a Jupyter notebook. Everything works fine and there's definitely an image read and can be displayed because I've tested it with openCV's imshow() function (and the image pops up). However, when I tried opening the image with plt.imshow() and plt.show(), the image would not appear. I went online to search for solution at they suggested its a backend issue? However, when I ran
