To set the title and size of a PyQt5 window, you can use the methods of the QMainWindow class. Here is a simple example code:

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow

app = QApplication(sys.argv)

# 创建一个窗口
window = QMainWindow()
window.setWindowTitle('My PyQt5 Window')  # 设置窗口标题
window.setGeometry(100, 100, 800, 600)  # 设置窗口大小和位置

window.show()
sys.exit(app.exec_())

In the code above, a QApplication instance is created first, followed by the instantiation of a QMainWindow object. The window title is set using the setWindowTitle() method, and the window position and size are set using the setGeometry() method. Finally, the window is displayed by calling show() method, and the application’s event loop is started by calling app.exec_() method.
