python-3.7

问题 I am simply trying to get the value of column ' ID ' where two rows meet (meet where Name and Zip are on the same row) then with that row number, I get column ' ID ' value to rename file with. I don't think writing the ' .rename ' correctly for one.. any pointers appreciated. Currently no error, but no output either. import PyPDF2 from PyPDF2 import PdfFileWriter, PdfFileReader import re import config import xlrd import numpy as np import pandas as pd import math import os for filename in os

问题 When building and installing Python 3.7.0 from source on openSUSE Leap 42.3 there are serious python errors with the default ./configure which installs to /usr/local . (openSUSE Leap 42.3 Python3 package is only up to Python 3.4.6, and virtualenv does not yet have the release version 3.7.) $ python3 Python 3.7.0 (default, Jul 5 2018, 15:55:09) [GCC 4.8.5] on linux Type "help", "copyright", "credits" or "license" for more information.

问题 I have the following class: class WordItem: def __init__(self, phrase: str, word_type: WORD_TYPE): self.id = f'{phrase}_{word_type.name.lower()}' self.phrase = phrase self.word_type = word_type @classmethod def from_payload(cls, payload: Dict[str, Any]) -> 'WordItem': return cls(**payload) How can I rewrite this class as a dataclass? Specifically, how should the id field be declared? It has a generated value, and is not a field that the code creating instances would provide. 回答1: Just move

问题 I'm trying to get a bot that will repeat what a user inputs, as many times as the user specifies. The issue I'm running into is that if the user types: !repeat 5 x y , the bot will only repeat x 5 times, and not x y 5 times. This is the code I'm trying to run: @bot.command() async def repeat(times: int, content="Repeating..."): for i in range(times): if times > 10: await bot.say("Cannot spam more than 10 messages at a time.") return else: await bot.say(content) 回答1: You can use the keyword

问题 I have created a simple maze and I have no way to move the character to the objective. The maze is on a TKinter window so I don't know if that is stopping the code from running. I have tried using pynput, which has worked in a seperate program without a tkinter window running, so I dont get whats wrong at all. def level1(): x=1 startx = 1 objectivex = 10 y=1 starty=1 objectivey=10 val_in_row = [[0,1,2,3,4,5,6,7,8,9,10,11],[0,3,7,11],[0,1,5,7,8,9,11],[0,3,5,6,11],[0,2,4,7,9,10,11],[0,4,6,10,11

问题 I wanted to ask, is it possible to put the Update and On_Draw functions of a Pyglet class created by the user in a thread? Let me explain. I have the class of my app of Pyglet, in which I need some functions (always of the same class) that work simultaneously with the Update and On_Draw functions. Now, I've been looking around and the only things I've found is inserting the entire Pyglet app into a main thread, but doing so would give problems to the Pyglet itself. I just need to have those

问题 I am preprocessing text data. However, I am facing issue with lemmatizing.

问题 I have a list of lists roots_3 = [['4', '5', '10'], ['11', '12', '13'], ['0', '17', '26'], ['1', '10', '15'], ['4', '19', '26'], ['11', '14', '22'],.... ] and I want to turn all the values inside in integer so I wrote a loop for i in range(len(roots_3)): for j in range(len(roots_3[i])): roots_3[i][j]= np.int(roots_3[i][j]) and this is the error I get : ValueError: invalid literal for int() with base 10: '\x00\x00\x00... Note that roots_3 is obtained from several text files like this: for file
