Type Error: argument 1 has unexpected type 'QPushButton'

I wrote this codes:
import sys
import os
from PyQt5 import QtWidgets
class Notepad(QtWidgets.QWidget):
def __init__(self):
super().__init__()
self.init_ui()
def init_ui(self):
self.yazi_alani = QtWidgets.QTextEdit()
self.temizle = QtWidgets.QPushButton("Temizle")
self.kaydet = QtWidgets.QPushButton("Kaydet")
self.dosya_ac = QtWidgets.QPushButton("Dosya Aç")
v_box = QtWidgets.QVBoxLayout()
v_box.addWidget(self.yazi_alani)
v_box.addWidget(self.temizle)
v_box.addWidget(self.kaydet)
v_box.addWidget(self.dosya_ac)
self.setLayout(v_box)
self.setWindowTitle("Barış'ın Notepad Programı")
self.setGeometry(200,200,800,600)
self.temizle.clicked.connect(self.temizle)
self.kaydet.clicked.connect(self.kaydet)
self.dosya_ac.clicked.connect(self.dosya_ac)
self.show()
def temizle(self):
self.yazi_alani.clear()
def kaydet(self):
dosya_ismi = QtWidgets.QFileDialog.getSaveFileName(self,"Dosya Kaydet",os.getenv("HOME"))
with open (dosya_ismi[0],"w",encoding="utf-8") as file:
file.write(self.yazi_alani.toPlainText())
def dosya_ac(self):
dosya_ismi = QtWidgets.QFileDialog(self, "Dosya Aç", os.getenv("HOME"))
with open(dosya_ismi[0],"r",encoding="utf-8") as file:
self.yazi_alani.setText(file.read())
app = QtWidgets.QApplication(sys.argv)
pencere = Notepad()
sys.exit(app.exec())
I got this error:
Traceback (most recent call last):

How can I solve this error?
It may be good if you answer fast...

You should rename your buttons or funcions.
You've got here method Notepad.temizle() AND button Notepad.temizle
So when you expect to send a message, instead you send a button, which is typeError
Also I can see the same error with other methods

AttributeError: 'AxesSubplot' object has no attribute 'set_canvas'

Good morning,
I am using tkinter with matplotlib but I am facing a problem which I will write down.
I tried many solution but nothing worked, so if you had faced the problem before or if you just know it help me please with it.
Here is my code:
import matplotlib
matplotlib.use('TkAgg')
from tkinter import *
import tkinter.simpledialog
import matplotlib.pyplot as plt
import datetime
from matplotlib.figure import Figure
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
root = Tk()
root.geometry('1000x600')
middle = Frame(root)
middle.pack()
payments = {'.':0}
m = datetime.datetime.now()
def digram1():
global m
purpose = list(payments.keys())
amounts = list(payments.values())
plt.plot((purpose),(amounts))
plt.xlabel('Purpose')
plt.ylabel('Amounts')
plt.title('Outgoings for the '+ str(m.month)+'th month\n'+str(datetime.date.today()))
plt.show
fig = Figure(figsize=(5,5),dpi = 100)
ex = fig.add_subplot(111)
canvas = FigureCanvasTkAgg(ex,master=root)
canvas.show()
canvas.get_tk_widget().pack(side =tk.top,fill=tk.Both, expand = True)
digram1m = Button(middle,text='1st digram',command=digram1, height = 5,width =15 , fg ='green')
digram1m.grid(row = 5 , column = 6 ,sticky=E)
root.mainloop()
and here is the output:
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Users\A\Anaconda3\lib\tkinter\__init__.py", line 1699, in __call__

figure.set_canvas(self)

I am using Jupyter notebook 5.4.0.
Thank you for your time..

Python timed subprocess.Popen

I have the following code which gets data from a webscrape.
I only just learnt how to use the
subprocess.Popen
and i am trying to ouse my initiative along with other answers to similar questions on how to use the
subprocess.Popen
to execute the script below to get the webscrape data into my insert field updated every 30 seconds or so. But it is not working. Please could you point me in the right direction?

the error i get is
error no 22: invalid syntax referring to the script between the

then multiple command line windows open displaying the same error and i have to shut down the computer to stop it!
i amended the reference to my file with the 'r' prefix as follows:
([r"C:\Users\.....\Desktop\..\Python27\.....\tester.py"])
but removed the python.exe call as it just calling up the command line window. Now, i receive the following error message:

WindowsError: [Error 193] %1 is not a valid Win32 application

Python uses backslash to quote characters, like \n = newline and \t = tab.
Use an r prefix to make a raw string literal, like a Windows file path:
out = subprocess.Popen([r"C:\Users\.....\Desktop\Py\python.exe", r"C:\Users\.....\Desktop\..\Python27\.....\tester.py"])

Python does not detect soundtouch elements (bpmdetect and pitch) in gst-plugins-bad

I have installed gstreamer, gst-plugins-bad and its python bindings.
The following code selects a song from a given directory and plays it.
import pygst
pygst.require("0.10")
import gst
import pygtk
import gtk
import os
class Main:
def __init__(self):
self.pipeline = gst.Pipeline("mypipeline")
self.musicFiles = os.listdir("musicFiles")
self.currentSong = self.musicFiles[0]
self.findFile = gst.element_factory_make("filesrc", "file")
self.findFile.set_property("location", "musicFiles/" + self.currentSong)
self.pipeline.add(self.findFile)
self.mad = gst.element_factory_make("mad", "mad")
self.pipeline.add(self.mad)
self.findFile.link(self.mad)
self.audioconvert = gst.element_factory_make("audioconvert", "convert")
self.pipeline.add(self.audioconvert)
self.mad.link(self.audioconvert)
self.audioresample = gst.element_factory_make("audioresample", "resample")
self.pipeline.add(self.audioresample)
self.audioconvert.link(self.audioresample)
self.getbpm = gst.element_factory_make("bpmdetect", "bpm")
self.pipeline.add(self.getbpm)
self.audioresample.link(self.getbpm)
self.sink = gst.element_factory_make("playsink", "sink")
self.pipeline.add(self.sink)
self.audioresample.link(self.sink)
self.pipeline.set_state(gst.STATE_PLAYING)
start=Main()
gtk.main()
However, when I try to create the bpmdetect element, it gives the following error:
Traceback (most recent call last):
File "/Users/shubhitsingh/Desktop/Stuff/COLLEGE/US/Carnegie Mellon/Fall '12/15-112/Term Project/Practice/gstreamertutorial-1.py", line 49, in <module>

self.getbpm = gst.element_factory_make("bpmdetect", "bpm")
ElementNotFoundError: bpmdetect
Other elements from gst-plugins-bad can be created without problems. Its just the two elements under soundtouch (bpmdetect and pitch) that cannot be created. Help?

Placing a Button in UltimateListCtrl using wxPython

I'm new to Pythong and I have been trying to get a button within UltimateListCtrl. I still can't figure out what I'm doing wrong. Here is my code:
try:
from agw import ultimatelistctrl as ULC
except ImportError: # if it's not there locally, try the wxPython lib.
from wx.lib.agw import ultimatelistctrl as ULC
self.table = ULC.UltimateListCtrl(self, -1, agwStyle=ULC.ULC_REPORT|
ULC.ULC_HAS_VARIABLE_ROW_HEIGHT)
self.table.InsertColumn(0, "Name")
self.table.InsertColumn(1, "Size")
self.table.InsertColumn(2, "Download")
for i in range(0, len(masterlist)):
pos = self.table.InsertStringItem(i,str(masterlist[i]['name']))
self.table.SetStringItem(pos, 1,str(masterlist[i]['size']))
button = wx.Button(self, id=i, label="Download")
self.table.SetItemWindow(pos, col=2, wnd=button, expand=True)
masterlist is a list of download items.
I get this traceback:
Traceback (most recent call last):
File "E:\TestApp.py", line 67, in Display
self.table.SetItemWindow(pos, col=5, wnd=button, expand=True)
File "C:\Python27\lib\site-packages\wx-2.8-msw-unicode\wx\lib\agw\ultimatelistctrl.py", line 12961, in SetItemWindow
return self._mainWin.SetItemWindow(item, wnd, expand)
File "C:\Python27\lib\site-packages\wx-2.8-msw-unicode\wx\lib\agw\ultimatelistctrl.py", line 9021, in SetItemWindow
item.SetWindow(wnd, expand)
File "C:\Python27\lib\site-packages\wx-2.8-msw-unicode\wx\lib\agw\ultimatelistctrl.py", line 1863, in SetWindow
mainWin = listCtrl._mainWin
AttributeError: 'MainWindow' object has no attribute '_mainWin'

button's parent should be your ULC i.e self.table
So change this line:
button = wx.Button(self, id=wx.ID_ANY, label="Download")
to this:
button = wx.Button(self.table, id=wx.ID_ANY, label="Download")
Update in response to comment:
For some reason it doesn't seem to be possible to delete all items in a ULC with the
DeleteAllItems() method if any of the items contain widgets so instead use DeleteItem().
def emptyList(self)
itemCount = self.list.GetItemCount()
for item in xrange(itemCount):
self.list.DeleteItem(0)
