In general the idea is to use a QLineEdit and to prevent the user from entering inappropriate values using a QRegExpValidator, for example assuming that you only want floating values to be entered, the following example only allows entering that type of values, spaces and commas by calculating the sum and showing the values in a QListWidget:
from PyQt5 import QtCore, QtGui, QtWidgets
class Widget(QtWidgets.QWidget):
def __init__(self, parent=None):
super(Widget, self).__init__(parent)
flay = QtWidgets.QFormLayout(self)
regex = r"^(s*(-|+)?d+(?:.d+)?s*,s*)+(-|+)?d+(?:.d+)?s*$"
validator = QtGui.QRegExpValidator(QtCore.QRegExp(regex), self)
self._le = QtWidgets.QLineEdit()
self._le.setValidator(validator)
self._list_widget = QtWidgets.QListWidget()
button = QtWidgets.QPushButton("Press me")
button.clicked.connect(self.on_clicked)
self._result_label = QtWidgets.QLabel(alignment=QtCore.Qt.AlignCenter)
flay.addRow("Input: ", self._le)
flay.addRow("Output: ", self._list_widget)
flay.addRow("Sum of values: ", self._result_label)
flay.addRow(button)
@QtCore.pyqtSlot()
def on_clicked(self):
self._list_widget.clear()
if self._le.text():
values = [float(val) for val in self._le.text().split(",")]
print(values)
self._list_widget.addItems([str(val) for val in values])
self._result_label.setText(str(sum(values)))
if __name__ == '__main__':
import sys
app = QtWidgets.QApplication(sys.argv)
w = Widget()
w.show()
sys.exit(app.exec_())
