在循环中动态更改方法名称？

Question

I am actually struggling while trying to change a method name within a loop. I am building a GUI with QT and I am facing the problem of repeating the same function but with a different name.

Here is my code:

from Config import Ui_Dialog

class Ui_Dialog_Useful(Ui_Dialog):

    def setupUi(self, widget):
        super().setupUi(widget)
        self.Sensitivity_filler()

    def Sensitivity_filler(self):
        self.Sensitivity_1.insertItems(0, ['10', '100', '1000'])
        self.Sensitivity_2.insertItems(0, ['10', '100', '1000'])
        self.Sensitivity_3.insertItems(0, ['10', '100', '1000'])
        self.Sensitivity_4.insertItems(0, ['10', '100', '1000'])
        self.Sensitivity_5.insertItems(0, ['10', '100', '1000'])
        self.Sensitivity_6.insertItems(0, ['10', '100', '1000'])
        self.Sensitivity_7.insertItems(0, ['10', '100', '1000'])
        self.Sensitivity_8.insertItems(0, ['10', '100', '1000'])

As you can see the only change between the functions is the name of the QComboBox object. I have to perform this several times. Is there a way to do that within a loop?

Thanks

Usually you shouldn't be doing this (ie dynamic names, since collections do this better), but since UI code tends to be tricky, you can use getattr to get the right object.

For example, you'd probably do:

for i in range(1, 9):
    getattr(self, 'Sensitivity_'+str(i)).insertItems(0, ['10', '100', '1000'])

If there's a way of doing this without using getattr , you should definitely use it. I'm not familiar with QT by any means. For example, if it's possible, you should be storing your sensitivity items as an iterable (ie self.sensitivities ) and iterating over that instead.
