Question

我正在创建一个tageditor，在＆＃34;＆＃34;之前显示一个mp3文件的ID3-Tags。＆＃34;后＆＃34;不同textLines中的样式。如果没有可用的标签，则不显示任何内容。你也可以编辑＆＃34;＆＃34;＆＃34; textLines和对它们所做的任何更改都应该保存到文件中，但当我按下button2时，我会得到底部的回溯。如何将第6-10行保存为新的＆＃34;音频[＆＃34;标题＆＃34;]，音频[＆＃34;艺术家＆＃34;]＆＃34;等等？ This is the GUI

import sys
import easygui

from mutagen.easyid3 import EasyID3
from PyQt5.QtCore import pyqtSlot
from PyQt5.QtWidgets import QApplication, QDialog
from PyQt5.uic import loadUi
from PyQt5.QtWidgets import QLineEdit
lied = None
error = "No ID3-Tag available."
class TrackTag1(QDialog):
    def __init__(self):
        super(TrackTag1,self).__init__()
        loadUi("TrackTag1.ui",self)
        self.setWindowTitle("TrackTag")

@pyqtSlot()
def on_button1_clicked(self):
    #root.fileName = filedialog.askopenfilename( filetypes = ( ("Musik Dateien", "*.mp3"), ("Alle Dateien", "*.*") ) )
    #print(easygui.fileopenbox('MP3 Dateien','', '*.MP3'))
    lied = easygui.fileopenbox('MP3 Dateien','', '*.MP3')
    audio = EasyID3(lied)
    self.line0.setText(lied)                    #printing filepath to line0
    try:
        self.line1.setText(str(audio["title"]).strip("[']"))        #printing the ID3 tags after they've been stripped of "['']"
        self.line6.setText(str(audio["title"]).strip("[']"))
    except:
        KeyError
        self.line1.setText(error)
    try:
        self.line2.setText(str(audio["album"]).strip("[']"))
        self.line7.setText(str(audio["album"]).strip("[']"))
    except:
        KeyError
        self.line2.setText(error)
    try:
        self.line3.setText(str(audio["date"]).strip("[']"))
        self.line8.setText(str(audio["date"]).strip("[']"))
    except:
        KeyError
        self.line3.setText(error)
    try:
        self.line4.setText(str(audio["artist"]).strip("[']"))
        self.line9.setText(str(audio["artist"]).strip("[']"))
    except:
        KeyError
        self.line4.setText(error)
    try:
        self.line5.setText(str(audio["genre"]).strip("[']"))
        self.line10.setText(str(audio["genre"]).strip("[']"))
    except:
        KeyError
        self.line5.setText(error)

def on_button2_clicked(self):
    audio = EasyID3(lied)
    audio["title"] = self.line6.text()
    audio.save()



app=QApplication(sys.argv)
widget=TrackTag1()
widget.show()
sys.exit(app.exec_())




app=QApplication(sys.argv)
widget=TrackTag1()
widget.show()
sys.exit(app.exec_())

当我按下保存更改按钮时，我收到了此追溯：

Traceback (most recent call last):
  File "<string>", line 69, in on_button2_clicked
  File "h:\program files (x86)\python\lib\site-packages\mutagen\_util.py",     line 139, in wrapper
    writable, create) as h:

    return next(self.gen)
  File "h:\program files (x86)\python\lib\site-packages\mutagen\_util.py",     line 270, in _openfile
    raise TypeError("Missing filename or fileobj argument")
TypeError: Missing filename or fileobj argument

目前，您应该只能编辑代码，但我打算尽快实施MusicBrainz查询。

Answer 1

在on_button2_clicked方法中，lied对象基本上是None。要获得正确的，请在on_button1_clicked中分配关键字global。（你实际上从来不应该这样做！而是创建一个属性来存储它并通过self.lied或类似的方式访问它）

另外，我假设由于self关键字而导致这两个函数是infact类方法，并且在复制粘贴时你只是缩进了缩进。

基本上是由于范围引起的错误。

尝试创建ID3-Tag编辑器。 TypeError：缺少文件名或fileobj参数
