Not Responding when using PyQt

Question

I just began to learn PyQt5 in python and the window which opens becomes not responding

import sys
import PyQt5
from PyQt5 import QtWidgets
from PyQt5 import QtCore
x=QtWidgets.QApplication(sys.argv)
y=QtWidgets.QWidget()
y.show()

Answer 1

Try adding the following line to the end of your code:

sys.exit(x.exec_())

I would also recommend following a tutorial such as this one as PyQt does have a framework which needs to be followed closely. (http://zetcode.com/gui/pyqt5/firstprograms/)
