问题 Using Pycharm to write a python script for loading and formatting a fixed width file I'm getting different results when I run the script in terminal (within Pycharm or locally) and when using the run option in Pycharm. Any reason why this is the case and which is correct? with open('uk_dcl_mrg.txt', 'rb') as f: ct = 0 for line in f: ct += 1 #### OUTOUT #### for i in layout: ## Loop to create dictionary headerdict[i[0]] = line[i[1]:i[2]] if (headerdict['CORP-STATUS-IND'] == "\x9f"): headerdict

问题 I'm writing a Python program to interact with a device based on a CAN Bus. I'm using the python-can module successfully for this purpose. I'm also using asyncio to react to asynchronous events. I have written a "CanBusManager" class that is used by the "CanBusSequencer" class. The "CanBusManager" class takes care of generating/sending/receiving messages, and the CanBusSequencer drives the sequence of messages to be sent. At some point in the sequence I want to wait until a specific message is

问题 I'm trying to run a Windows executable inside my application written in Python using PyQt5. I'm fairly new to using PyQt5 but trying. The problem I'm facing is actually getting the EXE in question to run within my applications Frame, Window or QWidget. At the moment I don't need to send or get responses/results to and from the Windows executable, I only need the ability to show it within my application. class MyWindow(QWidget): def __init__(self): super().__init__() self.initUI() def initUI

问题 I'm having trouble figuring this one out -- when trying to install a package (zipline in this case), it's struggling to find the setuptools.build_meta file, which I DO HAVE in the site-packages\setuptools directory. As ignorant as I am, I tried dropping this file into the site-packages\pip_vendor\pep517 directly with no change. I'm sure this is simple, but I'm not seeing it. Any help would be appreciated! The trace back is below. ERROR: Exception: Traceback (most recent call last): File "C:
