Aligning a QTableWidgetItem causes item to be None

I have created a table in PyQt5 and populated it similar to how it's done in this post. I want to center align all the cells but when I try to align each cell my QTableWidgetItem becomes None.

According to the docs setTextAlignment(QtCore.Qt.AlignVCenter | QtCore.Qt.AlignHCenter) should work. See here too

Here is a working example where self.db_table is the QTableWidget.

for row in rows:
    inx = rows.index(row)
    self.db_table.insertRow(inx)
    self.db_table.setItem(inx, 0, QTableWidgetItem(str(row[0])))
    self.db_table.setItem(inx, 1, QTableWidgetItem(str(row[1])))
    self.db_table.setItem(inx, 2, QTableWidgetItem(str(row[2])))
    self.db_table.setItem(inx, 3, QTableWidgetItem(str(row[3])))
    self.db_table.setItem(inx, 4, QTableWidgetItem(str(row[4])))

And when I add the setTextAlignment() it makes all the QTableWidgetItems None:

for row in rows:
    inx = rows.index(row)
    self.db_table.insertRow(inx)
    self.db_table.setItem(inx, 0, QTableWidgetItem(str(row[0])).setTextAlignment(QtCore.Qt.AlignVCenter | QtCore.Qt.AlignHCenter))
    self.db_table.setItem(inx, 1, QTableWidgetItem(str(row[1])).setTextAlignment(QtCore.Qt.AlignVCenter | QtCore.Qt.AlignHCenter))
    self.db_table.setItem(inx, 2, QTableWidgetItem(str(row[2])).setTextAlignment(QtCore.Qt.AlignVCenter | QtCore.Qt.AlignHCenter))
    self.db_table.setItem(inx, 3, QTableWidgetItem(str(row[3])).setTextAlignment(QtCore.Qt.AlignVCenter | QtCore.Qt.AlignHCenter))
    self.db_table.setItem(inx, 4, QTableWidgetItem(str(row[4])).setTextAlignment(QtCore.Qt.AlignVCenter | QtCore.Qt.AlignHCenter))

Is there any reason why this isnt working?

the setTextAlignment() method does not return any parameters and that equals None, and then you are passing None to setItem, what you must do is create the item as item = QTableWidgetItem({}) and then use item.setTextAlignment({}) and at the end add it self.db_table.setItem(inx, 0, item) for each element, a reduced form is the following:

for row in rows:
    inx = rows.index(row)
    self.db_table.insertRow(inx)
    for i, v in zip(range(5), row):
        item = QTableWidgetItem(str(v))
        item.setTextAlignment(QtCore.Qt.AlignVCenter | QtCore.Qt.AlignHCenter)
        self.db_table.setItem(inx, i, item)
