Does anyone know why I can't open my Python programs?

Uwe123671ByUwe123671

For example, I've just written a program for taking notes, with cool functions and so on. I can run this Python script normally. However, a simple browser or something similar only opens for 1 millisecond, or I can open it, but an error message pops up saying "qt5core.dll is missing." But when I add all the "missing" DLL files, the browser still doesn't work, or the error dialog doesn't go away. If anyone knows what's causing this, please let me know. Thanks!

You need to download a Python compiler that your PC knows what Python is. As a review use the website Programiz

Ooh, that’s the problem.

I guess you didn’t install Qt properly.

this is the code for the browser(I have already tried everything, even from a tutorial but nothing goes):

import sys
from PySide2.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QLineEdit, QPushButton, QWidget, QHBoxLayout
from PySide2.QtWebEngineWidgets import QWebEngineView

class Browser(QMainWindow):
   def __init__(self):
       super().__init__()
       self.setWindowTitle("Einfacher Browser")
       self.setGeometry(300, 100, 1200, 800)

       self.browser = QWebEngineView()
       self.browser.setUrl("https://www.google.com")

       self.url_bar = QLineEdit()
       self.url_bar.setPlaceholderText("URL eingeben und Enter drücken...")
       self.url_bar.returnPressed.connect(self.navigate_to_url)

       self.back_button = QPushButton("<")
       self.back_button.clicked.connect(self.browser.back)

       self.forward_button = QPushButton(">")
       self.forward_button.clicked.connect(self.browser.forward)

       self.reload_button = QPushButton("⟳")
       self.reload_button.clicked.connect(self.browser.reload)

       nav_bar = QHBoxLayout()
       nav_bar.addWidget(self.back_button)
       nav_bar.addWidget(self.forward_button)
       nav_bar.addWidget(self.reload_button)
       nav_bar.addWidget(self.url_bar)

       main_layout = QVBoxLayout()
       main_layout.addLayout(nav_bar)
       main_layout.addWidget(self.browser)

       container = QWidget()
       container.setLayout(main_layout)
       self.setCentralWidget(container)

   def navigate_to_url(self):
       url = self.url_bar.text()
       if not url.startswith("http"):
           url = "http://" + url
       self.browser.setUrl(url)

if __name__ == "__main__":
   app = QApplication(sys.argv)
   window = Browser()
   window.show()
   sys.exit(app.exec_())

And what if you import PySide PyQt5/6 instead?

And what?

sys.exit(app.exec_())

do they?
