Input dialog in PyQt is supported out of the box (QInputDialog). This has an input text, an ok and cancel button.

In this article you’ll see that works in PyQt. As shown in the screenshot

from PyQt5.QtWidgets import (QWidget, QPushButton, QLineEdit, QInputDialog, QApplication, QLabel)
import sys

class Example(QWidget):

    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        # Add button                                                                                                     
        self.btn = QPushButton('Show Input Dialog', self)
        self.btn.move(30, 20)
        self.btn.clicked.connect(self.showDialog)

	# Add label                                                                                                      
        self.le = QLabel(self)
	self.le.move(30, 62)
        self.le.resize(400,22)

        self.setGeometry(300, 300, 290, 150)
	self.setWindowTitle('Input dialog')
        self.show()


    def showDialog(self):
	text, ok = QInputDialog.getText(self, 'Input Dialog', 'Enter text:')
	if ok:
            self.le.setText(str(text))

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())

If you are new to Python PyQt, then I highly recommend this book.
