Python YouTube downloader with pytube crashes when I search for video

I am making a YouTube video downloader with Python. I made the design with PyQt and edited the code in IDLE. Here is the code.

The problem is, when I provide a link in the plainTextEdit box and press the pushButton, the application crashes. There must be some problem in on_search_clicked() as it is the only method I wrote and the rest is auto generated.

implementing buttons' functions on main instead on script from pyqt5

I created a GUI using Qt designer, and converted it into .py file.
I used to write the functions directly in the GUI .py file, but I've been told to separate the code into two files: one with only the GUI commands as been converted from Qt designer, and Main - that would work all of the buttons and widgets of the GUI.
Now, I've managed to import the GUI from different file, and when I run the script the GUI does come up, but when I try to write functions I seem to have troubles.
This is my main:
from PyQt5 import QtWidgets
from mainwin import Ui_MainWindow
import sys
class ApplicationWindow(QtWidgets.QMainWindow):
def __init__(self):
super(ApplicationWindow, self).__init__()
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.exitbtn.clicked.connect(self.exitclicked) ***this is the connection and function that I'm trying to make 'em work***
def exitclicked(self,Dialog):
sys.exit()
def main():
import sys
app = QtWidgets.QApplication(sys.argv)
application = ApplicationWindow()
application.show()
sys.exit(app.exec_())
if __name__ == "__main__":
main()
And I don't know if it's relevant, but this is my GUI converted from Qt designer.

Would love if someone can write the right syntax to be able to implement functions through main.
Thank you so much :D

Show and hide\close windows with user arguments using PyQt5

I am writing GUI app with the help of Qt Designer. The app consists of multiple windows, so when the user clicks the push button on one window, the next window should open and the current window should hide. I achieved this feature for going from window 1 to window 2. But I am not able to do this to move from window 2 to window 3. I think this might be because the window 2 gets user arguments.
Is there any way to hide the window which gets user arguments?
The code is as follows:
Class for main window:
import sys
from PyQt5 import QtCore, QtGui, QtWidgets
import user_data
class MainWindow(object):
def user_data(self):
self.user_data_window = QtWidgets.QMainWindow()

How do you want the QTreeView to show something if it does not tell you what to show?, a QTreeView what it does is show the content of some model, in your case you should use a QFileSystemModel.
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
...
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
model = QtWidgets.QFileSystemModel(self)
model.setRootPath(QtCore.QDir.rootPath())
self.treeView.setModel(model)
self.treeView.expandAll()
self.treeView.setRootIndex(model.index(QtCore.QDir.rootPath()))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())

Adding a simple clock to a GUI

I have some code for a very generic/blank GUI with some labels and pushbuttons and an LCD widget. I also have some code for a separate window which just uses an LCD widget to display the time. My question is how do I insert to code for the clock into the generic GUI code to make that LCD widget display the time?
from PyQt5.QtCore import QTime, QTimer
from PyQt5.QtWidgets import QApplication, QLCDNumber
class DigitalClock(QLCDNumber):
def __init__(self, parent=None):
super(DigitalClock, self).__init__(parent)
self.setSegmentStyle(QLCDNumber.Filled)
timer = QTimer(self)
timer.timeout.connect(self.showTime)
timer.start(1000)
self.showTime()
self.setWindowTitle("Digital Clock")
self.resize(150, 60)
def showTime(self):
time = QTime.currentTime()
text = time.toString('hh:mm')
if (time.second() % 2) == 0:
text = text[:2] + ' ' + text[3:]
self.display(text)
if __name__ == '__main__':
import sys
app = QApplication(sys.argv)
clock = DigitalClock()
clock.show()
sys.exit(app.exec_())
That's the code for the simple clock and I want to insert that into the following to make the LCD widget display the time like this one does:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_mainWindow(object):
def setupUi(self, mainWindow):
mainWindow.setObjectName("mainWindow")
mainWindow.resize(800, 600)

self.centralwidget.setObjectName("centralwidget")
self.Clock = QtWidgets.QWidget(self.centralwidget)
self.Clock.setGeometry(QtCore.QRect(60, 420, 120, 80))
self.Clock.setObjectName("Clock")
self.DigitalClock = QtWidgets.QLCDNumber(self.centralwidget)
self.DigitalClock.setGeometry(QtCore.QRect(110, 190, 64, 23))
self.DigitalClock.setDigitCount(8)
self.DigitalClock.setObjectName("DigitalClock")

self.pushButton_5.setObjectName("pushButton_5")
self.pushButton_6 = QtWidgets.QPushButton(self.centralwidget)
self.pushButton_6.setGeometry(QtCore.QRect(230, 150, 75, 23))
self.pushButton_6.setObjectName("pushButton_6")
self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(20, 60, 47, 13))
self.label.setObjectName("label")
self.label_2 = QtWidgets.QLabel(self.centralwidget)
self.label_2.setGeometry(QtCore.QRect(20, 120, 47, 13))
self.label_2.setObjectName("label_2")
self.label_3 = QtWidgets.QLabel(self.centralwidget)
self.label_3.setGeometry(QtCore.QRect(20, 160, 47, 13))
self.label_3.setObjectName("label_3")
mainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(mainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 21))
self.menubar.setObjectName("menubar")
mainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(mainWindow)
self.statusbar.setObjectName("statusbar")
mainWindow.setStatusBar(self.statusbar)
self.retranslateUi(mainWindow)
QtCore.QMetaObject.connectSlotsByName(mainWindow)
def retranslateUi(self, mainWindow):
_translate = QtCore.QCoreApplication.translate
mainWindow.setWindowTitle(_translate("mainWindow", "Sim Monitor"))
self.pushButton.setText(_translate("mainWindow", "PushButton"))
self.pushButton_2.setText(_translate("mainWindow", "PushButton"))
self.pushButton_3.setText(_translate("mainWindow", "PushButton"))
self.pushButton_4.setText(_translate("mainWindow", "PushButton"))
self.pushButton_5.setText(_translate("mainWindow", "PushButton"))
self.pushButton_6.setText(_translate("mainWindow", "PushButton"))
self.label.setText(_translate("mainWindow", "TextLabel"))
self.label_2.setText(_translate("mainWindow", "TextLabel"))
self.label_3.setText(_translate("mainWindow", "TextLabel"))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
mainWindow = QtWidgets.QMainWindow()
ui = Ui_mainWindow()
ui.setupUi(mainWindow)
mainWindow.show()
sys.exit(app.exec_())

Simple solution:
Assuming that the first file is called DigitalClock.py and the second main.py then it is only necessary to add the import to main.py and change the line that the QLCDNumber creates:
main.py
from DigitalClock import DigitalClock
# ...
self.DigitalClock = DigitalClock(self.centralwidget) # QtWidgets.QLCDNumber(self.centralwidget)
Long solution:
Promote the QLCDNumber to use the DigitalClock, you could take the guide of this other answer where you would exchange QVideoWidget with DigitalClock and PyQt5.QtMultimediaWidgets with DigitalClock.
The other way is to create a widget plugin so that it can be used directly in Qt Designer.

DigitalClockFile.py
from PyQt5.QtCore import QTime, QTimer
from PyQt5.QtWidgets import QApplication, QLCDNumber
class DigitalClock(QLCDNumber):
def __init__(self, parent=None):
super(DigitalClock, self).__init__(parent)
self.setSegmentStyle(QLCDNumber.Filled)
self.setDigitCount(10)
timer = QTimer(self)
timer.timeout.connect(self.showTime)
timer.start(1000)
self.showTime()
self.setWindowTitle("Digital Clock")
self.resize(150, 60)
def showTime(self):
time = QTime.currentTime()
text = time.toString('hh:mm:ss')
if (time.second() % 2) == 0:
text = text[:2] + ' ' + text[3:5]+' '+text[6:]
self.display(text)
if __name__ == '__main__':
import sys
app = QApplication(sys.argv)
clock = DigitalClock()
clock.show()
sys.exit(app.exec_())

Add all the three files in the single directory.Since you already implement DigitalClock dont add the clock in thi UI just inherit class generated by QtDEsigner and add your clock in the inherited transformedUI.py and simply running the main.py will achieve desired task.Hope it helps
