DHT22 Temp sensor causing Tkinter GUI to lag

Hi I've been trying to implement a DHT22 temperature and humidity sensor with Tkinter GUI where it updates regularly while using the GUI. This is done on a Raspberry Pi 4 using Python. However, while the numbers are updating correctly, it would cause the GUI freeze momentarily while updating the numbers. I have already tried multithreading, but it unfortunately didn't help. Is there any solution to this problem? Any help is greatly appreciated.
Here's the code:

Tkinter repeat process, with next button

i want to build simple tkinter,
the GUI will display a text and user need to read the text and save the audio. my code currently works but the process not repeatable, my target when user press "NEXT" button the process will repeat the process... and when user press the "END" button process will stop.
is there anywhere how to done it?
import sounddevice as sd
import soundfile as sf
from tkinter import *
def Voice_rec():
fs = 48000
# seconds
duration = 5
myrecording = sd.rec(int(duration * fs),
samplerate=fs, channels=2)
sd.wait()
return sf.write('save_audio.wav', myrecording, fs)
master = Tk()
import os, random
txtfile = random.choice(os.listdir(""))
txtread = "" + txtfile
with open(txtread, "r") as filek:
textfile=filek.read()
# Label(master, text=filek.read()).pack()
wrapper = LabelFrame(master,text="sound record")
wrapper.pack(fill="both",expand="yes",padx=20,pady=20)
lbl3 = Label(wrapper,text=textfile,borderwidth=2, relief="solid",bg = "red")
lbl3.config(font=("Courier", 20))
lbl3.pack()
#def next():
# import os, random
# txtfile = random.choice(os.listdir("path"))
# txtread = "path" + txtfile
# with open(txtread, "r") as filek:
# textfile=filek.read()
# Label(master, text=filek.read()).pack()
# wrapper = LabelFrame(master,text="sound record")
# wrapper.pack(fill="both",padx=20,pady=20)
# lbl3 = Label(wrapper,text=textfile,borderwidth=2, relief="solid",bg = "red")
# lbl3.config(font=("Courier", 20))
# lbl3.pack()
Label(wrapper, text=" Voice Recoder : "
)#.grid(row=0, sticky=W, rowspan=5)
b = Button(wrapper, text="Start", command=Voice_rec)
b.pack()
c = Button(wrapper, text="Next", command=next)
c.pack()
#b.grid(row=0, column=2, columnspan=2, rowspan=2,
# padx=5, pady=5)
mainloop()
above code i refer from this link : https://www.geeksforgeeks.org/build-a-voice-recorder-gui-using-python/

I would suggest you wrap this in a function:
txtfile = random.choice(os.listdir(""))
txtread = "" + txtfile
with open(txtread, "r") as filek:
textfile = filek.read()
which you can then link to your Next button to load a new file each time. Do not re-render the whole UI every time.
In other words, something like this:
master = Tk()
text_file = StringVar()
wrapper = LabelFrame(master, text="sound record")
wrapper.pack(fill="both", expand="yes", padx=20, pady=20)
lbl3 = Label(wrapper)
def next_audio():
path = "path/"
txtfile = random.choice(os.listdir(path))
txtread = os.join(path, txtfile)
with open(txtread, "r") as filek:
text_file.set(filek.read())
print(text_file.get())
lbl3.configure(text=text_file.get())
next_audio()
lbl3.configure(text=text_file.get(), borderwidth=2, relief="solid", bg="red")
lbl3.config(font=("Courier", 20))
lbl3.pack()
Not the best looking code but that was not the intention, just to try and use your code to show what I mean. Also perhaps a tip on Tkinter, rather use the grid geometry manager. pack and place are not best practice with modern Tkinter.
Hope this helped?!

Pause function in pygame mixer is not working

I am currently making a GUI with Tkinter that plays music. The program is able to correctly play the songs, and I am trying to implement a pause button. This is the code I have, does anyone know why this might not be working? I know the button is linked properly since I have tried printing something out when the button is clicked, and that works. Also, there are no error messages, the audio is just not pausing.

Insert while loop values to tkinter magic window

I have a code to create a "magic window" in python.
It should shows title, time and news.
I took news with function newz to loop (it should show the news on-by-on in Tkinter window)
I tried to insert it into tkinter label but it doesn't work(it just doesn't appear, but when I insert plain text to label it works), how could I do it? Here is the whole code with time functions and news function + tkinter
import tkinter as tk
from tkinter import *
import feedparser
import json
from time import sleep
import time
import os
startupscreen = tk.Tk()
startupscreen.title('Magic Mirror: Python Mod')
welcometext = tk.Label(startupscreen, font = ('caviar dreams', 40), bg='black', fg='white')
startupscreen.configure(background='black')
startupscreen.overrideredirect(True)
welcometext.config(text='日本')
welcometext.pack(side=LEFT, padx= 120, pady=80)
# Gets the requested values of the height and widht.
windowWidth = startupscreen.winfo_reqwidth()
windowHeight = startupscreen.winfo_reqheight()
# Gets both half the screen width/height and window width/height
positionRight = int(startupscreen.winfo_screenwidth()/3 - windowWidth/2)
positionDown = int(startupscreen.winfo_screenheight()/2 - windowHeight/2)
# Positions the window in the center of the page.
startupscreen.geometry("+{}+{}".format(positionRight, positionDown))
startupscreen.update()

def tickk(time3=''):
time4 = time.strftime(":%M:%S")
if time4 != time3:
time3 = time4
clock_frame2.config(text=time4)
clock_frame2.after(200, tickk)
def newz():
url = 'https://news.google.com/rss?hl=ja&gl=JP&ceid=JP:ja'
d = feedparser.parse(url)

lab.pack(anchor=SW, fill=X, padx=45)
masterclock = tk.Label(root)
masterclock.pack(anchor=NW, fill=X, padx=45)
masterclock.configure(background='black')
clock_frame = tk.Label(root, font = ('caviar dreams', 130), bg='black', fg='white')
clock_frame.pack(in_=masterclock, side=LEFT)

tick()
tickk()
newz() #here it doesnt work
root.attributes("-fullscreen", True)
root.configure(background='black')
startupscreen.destroy()
root.mainloop()

I don't know what you want to display but you have to use
source.config(text="some text")
root.after(1000, newz)
inside function newz
Something like this
#--- newz - start ---
def newz():
url = 'https://news.google.com/rss?hl=ja&gl=JP&ceid=JP:ja'
d = feedparser.parse(url)
news = list()
for i, entry in enumerate(d.entries, 1):
p = entry.published_parsed
sortkey = "%04d%02d%02d%02d%02d%02d" % (p.tm_year, p.tm_mon, p.tm_mday, p.tm_hour, p.tm_min, p.tm_sec)
tmp = {
"title": entry.title,
#"link": entry.link,
"sortkey": sortkey
}
news.append(tmp)
news = sorted(news, key=lambda x: x['sortkey'])
myDict = {}
for d in news:
c = d['title']
myDict[c] = myDict.get(c,0)+1
frequency = myDict.keys()
frequency = list(frequency)
for x in range(len(frequency)):
print(frequency[x])
source.config(text=str(frequency[x]))
x += 1
#source.config(text="some text")
root.after(1000, newz) # 1000ms = 1s
#--- newz - end ---

Tkinter Label not being updated with textvariable

In my code I see that the Label is not being updated with the 'textvariable', despite I believe I'm doing it right (probably not!).
varmuTemperature = StringVar(value="default value")
self.Label = Label(Frame2, textvariable = varmuTemperature)
self.Label.pack()
This should show a label with "default value" written on it. The problem is that I don't see anything written.
I have my code posted here.

Debugging a bit and start commenting lines of code, I see that the problem may come from the
f=plt.figure(0, figsize=(20,10))
Commenting this line (and all dependencies of this) makes the Label to be written.
Can someone help here, please? I don't get why the graphics can interfere in the Label.
Thanks a lot.

The general problem seems to be your management of instance variables and objects. You keep around as self.* variables, things you'll never need to reference again, like buttonCheckComAvailable, but fail to make self.* variables for things, like varmuTemperature, that you will need to reference later.
Object-wise, you do things that don't make sense:
make_window.mainloop()
as make_window is an object class, not an instance, and an instance of the class make_window won't respond to mainloop anyway as it contains a window but isn't one itself.
Here's my MCVE for your example code that makes varmuTemperature an instance variable and, just for demonstration purposes, sets it when the various buttons on the interface are clicked so you can see it's working:
from tkinter import *
from tkinter import ttk
class make_window():
def __init__(self):
self.win = Tk()
self.win.title("Test")
self.win.state("zoomed")
Frame1 = Frame(self.win)
self.comboBoxAvailableCOMPort = ttk.Combobox(Frame1, width=30)
self.comboBoxAvailableCOMPort['values'] = []
self.comboBoxAvailableCOMPort.pack(padx=5, pady=5, side=LEFT)
Button(Frame1, text="Check COM Available", command=self.CheckComAvailable).pack(padx=5, pady=10, side=LEFT)
Button(Frame1, text="Open COM Port", command=self.OnOpenCom).pack(padx=5, pady=10, side=LEFT)
Button(Frame1, text="Close COM Port", command=self.OnCloseCom).pack(padx=5, pady=10, side=LEFT)
Frame1.pack()
Frame2 = Frame(self.win, highlightbackground="red", highlightcolor="red", highlightthickness=1)
self.varmuTemperature = StringVar(value="default value")
Label(Frame2, textvariable=self.varmuTemperature).pack()
Button(Frame2, text="Close Program", command=self.OnCloseProgram).pack(expand=True, fill='x', anchor='s')
Frame2.pack()
def CheckComAvailable(self):
self.varmuTemperature.set("CheckCom")
def OnOpenCom(self):
self.varmuTemperature.set("OpenCom")
def OnCloseCom(self):
self.varmuTemperature.set("CloseCom")
def OnCloseProgram(self):
self.OnCloseCom()
exit()
window = make_window()
window.win.mainloop()
