问题 I am using a multiprocessing.Pool which calls a function in 1 or more subprocesses to produce a large chunk of data. The worker process creates a multiprocessing.shared_memory.SharedMemory object and uses the default name assigned by shared_memory .

At shutdown I'm seeing warnings from resource_tracker : /usr/local

问题 I am using python3.8 and mysql.connector. Can I parameterize a query that contains a LIKE clause and pass in active % wildcard(s)?

问题 Currently I'm in the process of making a program where you can both login and register and the username/password are stored in a separate .txt file. Registering is working fine, the username and password is written without issue but I am having issues with reading from the file in both userRegister and userLogin The .txt file is formatted by username,password and I was wondering how I would go about reading from the file with the intention of comparing loginUsername and loginPassword to

The Error: C:\Program Files

问题 Really strange issue here. I have a 64bit copy of Python 3.8.1 on my Mac (Catalina 10.15.2). I have successfully installed pygame via pip3 install pygame . Every time I run Python3 and import pygame, I get the successful message of hello from the pygame community... . However, if I run any program that requires an import of pygame, the icon for my python launcher just loops and loads for an infinite amount of time. I get no error messages. I literally get nothing.

问题 I want to install HP driver (hplip) on my Ubuntu. It tries to install d-bus python package, but fails and says to install it manually. Installation with "apt" works fine, but maybe not for my main Python version and that's why hplip failed: sudo apt install -y dbus ... works well timofei@timofei:~/Downloads$ python Python 3.8.0 (default, Oct 28 2019, 16:14:01) [GCC 8.3.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import dbus Traceback (most recent

问题 I found similar posts, mostly related to linux on venv having an issue with working. python 3.8 venv missing activate command However, I am confused on how to solve it on windows, and what is happening.

问题 I am trying to figure out how to categorize commands in Click to resemble something close to the structure that kubectl uses in the way it separate commands out.
