从pythonscript导入变量-->解析导致的TypeError

Question

我一直在尝试用gtts构建一个speech-recognition应用程序。我现在想做的是使用另一个python脚本中的变量，这样我就可以更新tk标签了。我试图将我的代码放在一个类的结构中来访问这个变量。我添加了一个较小的程序来展示我的问题。(这些程序是同时运行的)我是Python的初学者，所以我希望你们能教我怎么做得更好。:)提前谢谢！

错误：

S = SuperAssistant()
TypeError: __init__() missing 1 required positional argument: 'audio'

展示我的问题的基本示例：

from try_access_var import myfunction 

print(myfunction.audio)

然后在我另一个名为try_access_var的pyscript中：

def myfunction():
    audio = 1

(我想在我的程序中实现我可能得到的解决方案)

`from gtts import gTTS
import speech_recognition as sr
from playsound import playsound
import os
import re
import webbrowser
from tkinter import *
import smtplib
import requests
import sys
import subprocess
from subprocess import Popen
import time
import datetime as dt
from datetime import timedelta
import keyboard
import mouse
import pyaudio
import tkinter as tk
from tkinter import filedialog, Text
import csv

请注意，“SuperAssistant类”属于代码

SuperAssistant类：

    self.audio = audio
    
    

def talkToMe(self):
    "speaks audio passed as argument"

    #SuperAssistant.audio = audio
    print(self.audio)

    tts.save("good.mp3")

    #for line in audio.splitlines():
     #   os.system("say " + audio)

    #use the system's inbuilt say command instead of mpg123
    #text_to_speech = gTTS(text=audio, lang='en')

我用subprocess.Popen(....)打开的小程序(show tk window)的代码。

Answer 1

SuperAssistent没有名为audio的类属性。为此，您必须将其设置在您的类中的某个位置。例如，您可以在talkToMe中执行类似SuperAssistent.audio = audio的操作。

是否有意只使用类方法而不实例化SuperAudio？如果不是这样，您应该添加一个构造函数，并添加self作为所有非类方法的第一个参数。如果是这样的话，我建议先介绍一下Python类/对象，比如this one on w3schools。

更新：

下面是一个使用脚本和类定义的拆分文件来设置和访问类和实例属性的示例：

example.py

class Foo():
    class_attribute = 'class attribute: initial value'

    def __init__(self):
        self.instance_attribute = \
            'instance attribute ({:X}): initial value'.format(id(self))

    def do_something(self = None):
        Foo.class_attribute = 'class_attribute: modified value'
        if self is not None:
            self.instance_attribute = \
                'instance attribute ({:X}): modified value'.format(id(self))

script.py

#!/usr/bin/env python3

from example import Foo

a = Foo()
b = Foo()

print(Foo.class_attribute)
print(a.instance_attribute)
print(b.instance_attribute)

print('\nChanging attributes..\n')
Foo.do_something()
a.do_something()
b.do_something()

print(Foo.class_attribute)
print(a.instance_attribute)
print(b.instance_attribute)

执行script.py会产生以下输出(请注意，ID在不同的机器和执行过程中会发生变化：

class attribute: initial value
instance attribute (7F640ACF56A0): initial value
instance attribute (7F640AC2AB50): initial value

Changing attributes..

class_attribute: modified value
instance attribute (7F640ACF56A0): modified value
instance attribute (7F640AC2AB50): modified value
