在 p 中的 QTablewidget 中插入具有单键多值的字典

Question

For one of my automation i need to insert a dictionary with key in 1st column and multiple values attached to key in second column as shown in image above in qtablewidget.On googling i found some code but didnt get how data[row][col] represents dictionary.Need help in correcting this code or better way to write if it is incorrect

self.tableWidget.setRowCount(len(dict))
self.tableWidget.setColumnCount(2)
for row in range(len(dict)):
    for col in range(2):
        item = QtWidgets.QTableWidgetItem(data[row][col], 0)
        self.tableWidget.setItem(row, col, item)

Answer 1

The code you found is clearly for a different type of structure, which is probably something like this:

data = {
    0: ['a', 'b'],
    1: ['q', 'w'],
    ...
}

So in the case above accessing data[row][col] means that data[0][0] will be a , data[0][1] will be b , etc.

Besides that, in order to do what you're asking (which is not really related to the code you provided), you need to use setSpan() (it's a method of QTableView, from which QTableWidget is inherited).

In the following example, I'm cycling through dictionary keys, create the first column item and the "sibling" items from the values corresponding to each key, then I use setSpan with the first item row and column, with a row span set to the length of the values, and a column span set to 1.

Note that I'm using sorted(dict.keys()) for consistency, but if you're using Python >= 3.7 the keys are always sorted in the insertion order.

from PyQt5 import QtWidgets

structure = {
    'a.exe': [
        'a', 'b', 'c','d','e','f'
    ], 
    'b.exe': [
        'q', 'n', 'g', 'l', 'm', 'n', 'o'
    ]}

class Test(QtWidgets.QWidget):
    def __init__(self):
        super().__init__()
        layout = QtWidgets.QVBoxLayout(self)
        self.table = QtWidgets.QTableWidget()
        layout.addWidget(self.table)

        self.table.setColumnCount(2)
        for key in sorted(structure.keys()):
            values = structure[key]
            row = self.table.rowCount()
            self.table.insertRow(row)
            firstItem = QtWidgets.QTableWidgetItem(key)
            self.table.setItem(row, 0, firstItem)

            for i, value in enumerate(values):
                if i:
                    # add rows only from the second item
                    self.table.insertRow(row + i)
                item = QtWidgets.QTableWidgetItem(value)
                self.table.setItem(row + i, 1, item)

            # set the table span for the "key" item
            self.table.setSpan(firstItem.row(), 0, len(values), 1)


if __name__ == '__main__':
    import sys
    app = QtWidgets.QApplication(sys.argv)
    w = Test()
    w.show()
    sys.exit(app.exec_())
