python-3.7

I am Using PyQt5 and Py3.7, I am trying to loop through all my Qlistwidgets and save their string data, but also save all selected items on that widget. I slightly modified the loop from here , but am having some trouble getting the selected items to save and restore using the listwidget array loop. I checked the docs but can't seem to understand how to add additional options into the array (such as save all selected items), from the Qt docs for SetArrayIndex, here . My listWidgets have selectionMode set to MultiSelection. I am currently saving using this: def save_list_data(self): self

I'm using django ORM in a project(outside of django). My workflow is selecting objects by the django ORM and then send it to a message queue using an asyncio lib The problem is you can't call blocking functions in async environment and you can not use async/await in blocking environment. I have come up with 2 solutions: The whole program should be async. And use loop.run_in_executor to call blocking functions when needed. The whole program should be sync. And use asyncio.run() (Python 3.7) to call async functions needed. I can't decide which one is better approach. I know a similar question

I installed python 3.7 on my Windows 10 laptop since it has been officially released as of today (06/28/2018). Then i tried to install numpy package using pip pip install numpy The install proceeds but finally fails with the below error : source = func(extension, build_dir) File "numpy\core\setup.py", line 675, in get_mathlib_info raise RuntimeError("Broken toolchain: cannot link a simple C program") RuntimeError: Broken toolchain: cannot link a simple C program ---------------------------------------- Command ""c:\program files\python37\python.exe" -u -c "import setuptools, tokenize;__file__=

I'm currently trying my hands on the new dataclass constructions introduced in Python 3.7. I am currently stuck on trying to do some inheritance of a parent class. It looks like the order of the arguments are botched by my current approach such that the bool parameter in the child class is passed before the other parameters. This is causing a type error. from dataclasses import dataclass @dataclass class Parent: name: str age: int ugly: bool = False def print_name(self): print(self.name) def print_age(self): print(self.age) def print_id(self): print(f'The Name is {self.name} and {self.name} is

Before I begin, I'd like to preface that I'm relatively new to python, and haven't had to use it much before this little project of mine. I'm trying to make a twitter bot as part of an art project, and I can't seem to get tweepy to import. I'm using macOS High Sierra and Python 3.7. I first installed tweepy by using pip3 install tweepy and this appeared to work, as I'm able to find the tweepy files in finder. However, when I simply input import tweepy into the IDLE, I get this error: Traceback (most recent call last): File "/Users/jacobhill/Documents/CicadaCacophony.py", line 1, in <module>
