This is actually a brand-new feature as of Python 3.8. Added an = specifier to f-strings. An f-string such as f'{expr=}’ will expand to the text of the expression, an equal sign, then the representation of the evaluated expression. Essentially, it facilitates the frequent use-case of print-debugging, so, whereas we would normally have to write: … Read more
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
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
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
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/
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
