python-3.6

I recently transitioned from using SQLite for most of my data storage and management needs to MySQL. I think I've finally gotten the correct libraries installed to work with Python 3.6, but now I am having trouble creating a new table from a dataframe in the MySQL database. Here are the libraries I import: import pandas as pd import mysql.connector from sqlalchemy import create_engine In my code, I first create a dataframe from a CSV file (no issues here). def csv_to_df(infile): return pd.read_csv(infile) Then I establish a connection to the MySQL database using this def function: def mysql

I try to create a PyQt application. In order to run process in background and keep the PyQt5 application available for new instruction, I want to use multiprocessing . On the Windows OS, when I call a function from the Qt MainWindow class with multiprocessing.process , I have an error about pickling this class. But it is running find on Linux. Here is an example: #!/usr/bin/env python3 # -*- coding: utf-8 -*- import sys import multiprocessing # from PyQt5.QtWidgets import * from PyQt5.QtGui import * from PyQt5.QtCore import * class Frame_main(QMainWindow): def __init__(self, parent = None):

Consider the following example: import asyncio import tkinter as tk class App(tk.Tk): def __init__(self): super().__init__() self.create_widgets() self._configure_bindings() # I believe it is not possible # to do this if the method needs # to be async as well def create_widgets(self): pass def _configure_bindings(self): self.bind('<F5>', self.spam) # what's the proper way? # does this method need to be async as well? async def spam(self, event): await self.do_something() async def do_something(): pass async def run_tk(root): try: while True: root.update() await asyncio.sleep(.01) except tk

Update: Edited title to focus on the main problem. See my answer for full update. In the following code, a() and b() are identical. Each of them counts from 0 to 9 concurrently while acquiring and yielding a lock every 2 counts. import asyncio lock = asyncio.Lock() def a (): yield from lock.acquire() for i in range(10): print('a: ' + str(i)) if i % 2 == 0: lock.release() yield from lock.acquire() lock.release() def b (): yield from lock.acquire() for i in range(10): print('b: ' + str(i)) if i % 2 == 0: lock.release() yield from lock.acquire() lock.release() asyncio.get_event_loop().run_until

I'm trying to get the text stored in the clipboard by just using ctypes in Python 3.6 . I tested a lot of solutions I found on Stack and GitHub, but they only work for Python 2 to Python 3.4 . This is the code you'll find almost everywhere: from ctypes import * def get_clipboard_text(): text = "" if windll.user32.OpenClipboard(c_int(0)): h_clip_mem = windll.user32.GetClipboardData(1) windll.kernel32.GlobalLock.restype = c_char_p text = windll.kernel32.GlobalLock(c_int(h_clip_mem)) windll.kernel32.GlobalUnlock(c_int(h_clip_mem)) windll.user32.CloseClipboard() return text I tested it in Python 3

I'm trying to make a dive table that has some numbers that aren't in a pattern that I can see so I have to manually add all the values, but I need to grab the input and round it to the nearest number in the dictionary. I'll need to convert the input back to string for the output to be correct: CODE: class DepthTable: def __init__(self): self.d35 = {"10": "A", "19": "B", "25": "C", "29": "D", "32": "E", "36": "F", } def getpressureGroup(self, depth, time): if depth == "35": output = self.d35[time] else: output = "No info for that depth" print(output) if __name__ == "__main__": depthtable =
