PEP 572 contains many of the details, especially for the first question. I’ll try to summarise/quote concisely arguably some of the most important parts of the PEP: Rationale Allowing this form of assignment within comprehensions, such as list comprehensions, and lambda functions where traditional assignments are forbidden. This can also facilitate interactive debugging without the … Read more
Basically the problem seems to be that the underlying mmap’ed file (owned by shm within read_from_shm) is being closed when shm is garbage collected when the function returns. Then shmData refers back to it, which is where you get the segfault (for referring to a closed mmap) This seems to be a known bug, but … Read more
Well I know it’s not particularly helpful; but for me, this error was fixed simply by running my code on 3.7 instead of 3.8. There shouldn’t be any changes you have to make to your code, however (unless you were using walrus!) On Windows, this can be done with the -3.7 command line flag, as … Read more
I have found how to run Python 3.8 notebook on Colab. install Anaconda3 add (fake) google.colab library start jupyterlab access it with ngrok Here’s the code # install Anaconda3 !wget -qO ac.sh https://repo.anaconda.com/archive/Anaconda3-2020.07-Linux-x86_64.sh !bash ./ac.sh -b # a fake google.colab library !ln -s /usr/local/lib/python3.7/dist-packages/google \ /root/anaconda3/lib/python3.8/site-packages/google # start jupyterlab, which now has Python3 = 3.8 … Read more
This worked for me: matham commented 15 days ago We are not likely to release a 1.11.1 version for 3.8 to pypi. However, you can install kivy master using: pip install kivy[base] kivy_examples –pre –extra-index-url https://kivy.org/downloads/simple/
Spoiler alert!!! Applied #2.2. (from below) to the original .whls, and published them on [GitHub]: CristiFati/Prebuilt-Binaries – (master) Prebuilt-Binaries/PyWin32/v225 (win_amd64, win32 for Python 3.8). After installing (one of) them, existing code should work OOTB (with respect to this issue). Install steps: Download the .whl that matches your Python architecture (64bit, 32bit – for more details … Read more
From the Python 3.8 doc: The function time.clock() has been removed, after having been deprecated since Python 3.3: use time.perf_counter() or time.process_time() instead, depending on your requirements, to have well-defined behavior. (Contributed by Matthias Bussonnier in bpo-36895.)
The issue are the multiple nested loops. You have an application loop, so use it. Continuously move the ball in the loop: box.y -= box.vel_y box.x += box.vel_x Define a rectangular region for the ball by a pygame.Rect object: bounds = window.get_rect() # full screen or bounds = pygame.Rect(450, 200, 300, 200) # rectangular region … Read more
